openssl_conf environment variable

A file can include other files using the include syntax: If pathname is a simple filename, that file is included directly at that point. Seems like the next step is to submit a PR for that. OpenSSL applications can also use theCONFlibrary for their own purposes. It is equivalent to sending the ctrls SO_PATH with the path argument followed by LIST_ADD with value 2 and LOAD to the dynamic ENGINE. Setting OPENSSL_CONF=/dev/null would cause node to not use a conf file. Other applications may use an alternative name such as myapplication_conf . To perform certain cryptographic operations (creation of a private key, generation of a CSR, conversion of a certificate ...) on a Windows computer we can use the OpenSSL tool. This user has not uploaded their public key yet. set OPENSSL_CONF=C:\OpenSSL-Win32\bin\openssl.cfg set Path=.....Other Values here.....;C:\OpenSSL-Win32\bin Set OPENSSL_CONF Variable: Set Path Variable: Define the OPENSSL_CONF environmental variable. Perhaps something to reconsider if you agree. As with the providers, each name in this section identifies a section with the configuration for that name. Now set the environment variables to function OpenSSL properly on your system. [2012-01-03 21:25 UTC] dfroe at gmx dot de I am able to reproduce this bug under FreeBSD, too. Both LIBMYSQL_PLUGINS and OPENSSL_CONF allow custom modules to be loaded via Linux dynamic libraries.. If this exists and has a nonzero numeric value, any error suppressing flags passed to CONF_modules_load() will be ignored. The OpenSSL configuration looks up the value of openssl_conf in the default section and takes that as the name of a section that specifies how to configure any modules in the library. This example shows how to enforce FIPS mode for the application sample. See config(5) for a general description of the syntax of the config file. Ahh okay, thanks for clearing that up, The only issue with using a flag is that we are seriously reducing the usability of fips. This example shows how to use quoting and escaping. The name is the short name; the value is an optional long name followed by a comma, and the numeric value. PR to ignore OPENSSL_CONF: https://github.com/nodejs/node-private/pull/82, cc/ @rvagg @bnoordhuis @shigeki @mhdawson @gdams @sxa555. The name oid_section in the initialization section names the section containing name/value pairs of OID's. It is also possible to assign values to environment variables by using the name ENV::name, this will work if the program looks up environment variables using the CONF library instead of calling getenv() directly. To use a value from another section use $section::name or ${section::name}. The examples below assume the configuration above is used to specify the individual sections. If pathname is a directory, all files within that directory that have a .cnf or .conf extension will be included. The first part describes the general syntax of the configuration files, and subsequent sections describe the semantics of individual modules. A configuration file is divided into a number of sections. So are you saying that you're fine with loading an OpenSSL config file if OPENSSL_CONF=/path/to/file is set, but not ok with having a default location that always gets loaded if it exists (like /usr/local/ssl/openssl.cnf). Setup Environment Variables. @mhdawson @stefanmb See #10938 (comment) - I have no love for FIPS and it's not my department but doesn't a runtime knob weaken its security guarantees? Discussion of OPENSSL_FIPS: #3820 privacy statement. All other names are taken to be the name of a ctrl command that is sent to the ENGINE, and the value is the argument passed with the command. This probably is most useful for loading different key types, as shown here: The name engines in the initialization section names the section containing the list of ENGINE configurations. Not only are we unable to spawn child processes of node (such as in citgm) but I would also imagine that this prevents us from using clusters too? On Windows, run CMD (a command prompt) as Administrator. Add the Variable OPENSSL_CONF there. This specifies what digest the HASH-DRBG or HMAC-DRBG random bit generators will use. Now set the environment variables to function OpenSSL properly on your system. For example: Specifies the pathname of the module (typically a shared library) to load. Other random bit generators ignore this name. Running on Windows you might try: Set environment in local command window and verify problem: ENVIRONMENT VARIABLES The variable OPENSSL_CONF if defined allows an alternative configuration file location to be specified, it should contain the full path to the configuration file, not just its directory. First have this added to openssl.conf: [ san_env ] subjectAltName=${ENV::SAN} Then set the environment variable before invoking openssl: export SAN=DNS:value1,DNS:value2 openssl req -extensions san_env … A section begins with the section name in square brackets, and ends when a new section starts, or at the end of the file. Already on GitHub? Therefore, the following steps only are required for Service Providers prior to 2.x or Identity Providers. You can specify a different configuration file by using the OPENSSL_CONF environment variable or you can specify alternative configurations within one configuration file. Within the random section, the following names have meaning: This is used to specify the random bit generator. Under Windows 7 you find the settings dialog under: “Control Panel > System and Security > System > Advanced system settings (left menu) > Advanced (Tab) > Environment Variables…”. However, there was strong push from community members who wanted/needed the runtime switch for their use cases and so it was added in 6.x. So my question is what is the difference between the two commands below? A configuration file is divided into a number of sections. If the value is 0 the ENGINE will not be initialized, if the value is 1 an attempt is made to initialize the ENGINE immediately. The name alg_section in the initialization section names the section containing algorithmic properties when using the EVP API. , ; and _. Whitespace after the name and before the equal sign is ignored. All Rights Reserved. The value is a boolean that can be yes or no. If present, the module is activated. This command appends the OpenSSL binary path to your PATH and assign the configuration file path to OPENSSL_CONF. We can expect (for example) citgm ws to fail with: Please report problems with this website to webmaster at openssl.org. # Add environment variables to PowerShell profile # Test for a profile, if not found create one! This function was deprecated in OpenSSL 3.0; applications with configuration files using that syntax will have to be modified. Similarly, if a file is opened while scanning a directory, and that file has an .include directive that specifies a directory, that is also ignored. We are still using the same path so surely an attacker could still modify/change the config file? The docs also may need to mention that OPENSSL_ENGINE environment variable needs to be set if user wants to use an alternative SSLCryptoEngine in mod_ssl. This change was to prevent security issues caused by the misuse of the $OPENSSL_CONF variable. The path to the engines directory. Other modules are described in fips_config(5) and x509v3_config(5). This specifies that dollar signs are part of the symbol name and variable expansions must be specified using braces or parentheses. For example: The name random in the initialization section names the section containing the random number generater settings. The sections below use the informal term module to refer to a part of the OpenSSL functionality. If this is not the required behaviour then alternative ctrls can be sent directly to the dynamic ENGINE using ctrl commands. This specifies whether to initialize the ENGINE. It is not an error to leave any module in its default configuration. For example, foo$bar is treated as a single seven-character name. This change was to prevent security issues caused by the misuse of the $OPENSSL_CONF variable. The -query command uses only the symbolic OID names section and it can work without it. Bug 1402965 - Invalid guidance to set OPENSSL_CONF environment variable. Meta: I don't understand why FIPS is configurable at runtime in the first place. So it does not seem to be a Windows specific issue. It is an error if the value ends up longer than 64k. You are required to set OPENSSL_CONF and Path environment variables. OpenSSL also looks up the value of config_diagnostics. As with the providers, each name in this section identifies an engine with the configuration for that engine. The -query and -reply commands make use of a configuration file defined by the OPENSSL_CONF environment variable. This sets the property query used when fetching the random bit generator and any underlying algorithms. For example, to impose system-wide minimum TLS and DTLS protocol versions: The minimum TLS protocol is applied to SSL_CTX objects that are TLS-based, and the minimum DTLS protocol to those are DTLS-based. In order to support this, commands like openssl-req(1) ignore any leading text that is preceded with a period. Strings are all null terminated so nulls cannot form part of the value. Ignored in set-user-ID and set-group-ID programs. @rvagg perhaps you can explain this to me? The expansion and escape rules as described above that apply to value also apply to the pathname of the .include directive. You can override this reference in an openssl command with the -config option on the command line. Before running, set environment variables OPENSSL_CONF and SSLDIR to the directory where DemoCA was installed. The first part describes the general syntax of the configuration files, and subsequent sections describe the semantics of individual modules. This sets the default algorithms an ENGINE will supply using the function ENGINE_set_default_string(). Whitespace between the name and the brackets is removed. This page documents the syntax of OpenSSL configuration files, as parsed by NCONF_load(3)and related functions. The default name is openssl_conf, which is used by the openssl (1) utility. Since it it was windows in particular that doesn't store OpenSSL's conf file in a secure location by default, how about we bring back the default loading of the conf file on non-Windows, and the env var that controls the location? We can expect (for example) citgm ws to fail with: Allow OPENSSL_FIPS=enable to enable FIPS mode, but don't provide an equivalent to disable it, I don't think this causes any security issues. The section name can consist of alphanumeric characters and underscores. The security issue was that node unconditionally loaded a config file. Other modules are described in fips_config(5) and x509v3_config(5). Copyright © 1999-2018, OpenSSL Software Foundation. For compatibility reasons the SSLEAY_CONF environment variable serves the same purpose but its use is discouraged. Each path in the PATH environment variable should be separated by a semicolon. This is not the same as the formal term FIPS module, for example. I would have expected separate FIPS-only binaries. In addition the sequences \n, \r, \b and \t are recognized. This will work if the program looks up environment variables using the CONF library instead of calling getenv(3) directly. Ignored in set-user-ID and set-group-ID programs. The OPENSSL_CONF variable only influenced where it looked, not if. Using this name is deprecated, and if used, it must be the only name in the section. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Scroll Prev Top Next More. Copyright 2000-2021 The OpenSSL Project Authors. In these files, the dollar sign, $, is used to reference a variable, as described below. The default value is AES-256-CTR. The environment is mapped onto a section called ENV. This page documents the syntax of OpenSSL configuration files, as parsed by NCONF_load(3) and related functions. By default SEED-SRC will be used outside of the FIPS provider. For example: This loads and adds an ENGINE from the given path. Its behaviour isn't always what is wanted. OpenSSL 3.0 is a major release and consequently any application that currently uses an older version of OpenSSL will at the very least need to be recompiled in order to work with the new version. You signed in with another tab or window. Note: if Moodle fails to create a public key in Admin > Networking > Settings, you'll need to configurate your OPENSSL_CONF path. The text was updated successfully, but these errors were encountered: I am personally slightly confused as to what security difference there would be between using an environment variable to set the config file rather than passing it as a flag. Sign in With Windows File Explorer find openssl.cnf file (usually in your php/extras directory). The syntax for defining ASN.1 values is described in ASN1_genera… By debugging PHP, we noticed that PHP and its modules are using many environment variables to locate configuration files. The environment variable OPENSSL_CONF_INCLUDE, if it exists, will be prepended to all .include pathname's. By clicking “Sign up for GitHub”, you agree to our terms of service and The first section of a configuration file is special and is referred to as the default section. @bnoordhuis Separate FIPS-only binaries is how it worked in v4, it was changed for v6 as a result of #3819. The semantics of each module are described below. Two directives can be used to control the parsing of configuration files: .include and .pragma. Variables may also be passed from the environment of the shell which started the server using the PassEnv directive. If the # is the first non-space character in a line, the entire line is ignored. Adding it to the Path system variable is not sufficient! (This is only available on systems with POSIX IO support.) You must add the path to the OPENSSL_CONF system variable. Firstly, start to open Settings from the menu Windows and search for environment. 1 Main Changes in OpenSSL 3.0 from OpenSSL 1.1.1 [] 1.1 Major Release []. Setting the environment variable OPENSSL_CONF always works, but be aware that sometimes the default openssl.cnf contains entries that are needed by commands like openssl req. config - OpenSSL CONF library configuration files. This example shows how to expand environment variables safely. This sets the randomness source that should be used. if (-not (Test-Path $profile) ) { New-Item -Path $profile -ItemType File -Force } # Edit profile to add these lines '$env:path = "$env:path;C:\Program Files\OpenSSL\bin"' | Out-File $profile -Append … Then sign the certificate as follows: openssl ca -in tempreq.pem -out server_crt.pem It is possible to escape certain characters by using any kind of … In certain circumstances, such as with Certificate DNs, the same field may occur multiple times. Install OpenSSL on a windows machine. For example: This specifies what cipher a CTR-DRBG random bit generator will use. The name providers in the initialization section names the section containing cryptographic provider configuration. Upgrade to OpenEdge 11.6.3 Service Pack, 11.7.0 or later, where the certutil script has been updated to include the OPENSSL_CONF environment variable Workaround On UNIX/Linux Older versions will treat it as an assignment, so care should be taken if the difference in semantics is important. It might be a discussion we should reconsider, but I guess people want to use their FIPS node binaries to npm install things. Specifically, the backslash character was not an escape character and could be used in pathnames, only the double-quote character was recognized, and comments began with a semi-colon. On Windows, it was in a location that is usually writable by other users. This can be worked around by specifying a default value in the default section before the variable is used. You are required to set OPENSSL_CONF and Path environment variables. Have a question about this project? If it exists, it is applied whenever an SSL_CTX object is created. Rename it as openssl.conf. For example: The value consists of the string following the = character until end of line with any leading and trailing whitespace removed. This section is usually unnamed and spans from the start of file until the first named section. By using $ENV::name, the value of the specified environment variable will be substituted. There is no way to include characters using the octal \nnn form. Each section starts with a line [ section_name ]and ends when a new section is started orend of file is reached. Variables must be defined before their value is referenced, otherwise an error is flagged and the file will not load. Set the OPENSSL_CONF environment variable to the location of your OpenSSL configuration file. However this means it is no longer possible to test that the FIPS binary actually fails as expected in CitGM. https://www.openssl.org/source/license.html. The path to the directory with OpenSSL modules, such as providers. As a general rule, the pathname should be an absolute path. Typically, this file is located in the bin/ subdirectory of your OpenSSL installation directory. If called before OPENSSL_config()no configuration takes place. The phrase "in the initialization section" refers to the section identified by the openssl_conf or other name (given as openssl_init in the example above). In this case the command: perl -S CA.pl can be used and the OPENSSL_CONF environment variable changed to point to the correct path of the configuration file "openssl.cnf". While some OpenSSL commands have their own section for specifying OID's, this section makes them available to all commands and applications. My solution was to pass subjectAltName via an environment variable. The optional path to prepend to all .include paths. Ignored in set-user-ID and set-group-ID programs. The most basic way to set an environment variable in Apache is using the unconditional SetEnv directive. Within an engine section, the following names have meaning: This is used to specify an alternate name, overriding the default name specified in the list of engines. Create an environmental variable called OPENSSL_CONF and give it a value of: C:\ca\ca.cfg. If present, it must be first. On some platforms, however, it is common to treat $ as a regular character in symbol names. Within a provider section, the following names have meaning: This is used to specify an alternate name, overriding the default name specified in the list of providers. I'm not a huge fan of the side channel nature of environment variables, though. Any errors are ignored. The OpenSSL CONF library can be used to read configuration files; see CONF_modules_load_file(3). We’ll occasionally send you account related emails. It is used for the OpenSSL master configuration file openssl.cnf andin a few other places like SPKAC files and certificate extension files for the x509 utility. So rather than opening the prompt each time as an admin and then having to add the openssl path each time you just need to edit your system environment variables and add the path as instructed: OPENSSL_CONF=c:\[PATH TO YOUR OPENSSL DIRECTORY]\bin\openssl.cfg. Further calls to OPENSSL_config() will have noeffect. Allow enabling FIPS mode from an environment variable. It is possible to escape certain characters by using a single ' or double " quote around the value, or using a backslash \ before the character, By making the last character of a line a \ a value string can be spread across multiple lines. The FIPS provider uses call backs to access the same randomness sources from outside the validated boundary. https://github.com/nodejs/node-private/pull/82. Any sub-directories found inside the pathname are ignored. Within the algorithm properties section, the following names have meaning: The value may be anything that is acceptable as a property query string for EVP_set_default_properties(). An undocumented API, NCONF_WIN32(), used a slightly different set of parsing rules there were intended to be tailored to the Microsoft Windows platform. The engine-specific section is used to specify how to load the engine, activate it, and set other parameters. OPENSSL_no_config() disables configuration. The previous command modifies the environment variable OPENSSL_CONF which forces the openssl tool to look for a configuration file in an alternative location (in this case, ~/myCA/caconfig.cnf to switch back to the CA configuration). This environmental variable references the configuration file used by the openssl commands. Included files can have .include statements that specify other files. A comment starts with a # character; the rest of the line is ignored. If the init command is not present then an attempt will be made to initialize the ENGINE after all commands in its section have been processed. As of cae9eb3, it is no longer possible to enable FIPS mode with an environment variable. The name ssl_conf in the initialization section names the section containing the list of SSL/TLS configurations. The configuration file is a text file and comprises several sections, such as: The ca section, which configures the CA. Blank lines, and whitespace between the elements of a line, have no significance. First place to as the formal term FIPS module, activate it, and subsequent sections describe the of.
