OPENSSL-ENV(7)                      OpenSSL                     OPENSSL-ENV(7)



NAME
       openssl-env - OpenSSL environment variables

DESCRIPTION
       The OpenSSL libraries use environment variables to override the
       compiled-in default paths for various data.  To avoid security risks,
       the environment is usually not consulted when the executable is set-
       user-ID or set-group-ID.

       CTLOG_FILE
           Specifies the path to a certificate transparency log list.  See
           CTLOG_STORE_new(3).

       OPENSSL
           Specifies the path to the openssl executable. Used by the rehash
           script (see "Script Configuration" in openssl-rehash(1)) and by the
           CA.pl script (see "NOTES" in CA.pl(1)

       OPENSSL_CONF, OPENSSL_CONF_INCLUDE
           Specifies the path to a configuration file and the directory for
           included files.  See config(5).

       OPENSSL_CONFIG
           Specifies a configuration option and filename for the req and ca
           commands invoked by the CA.pl script.  See CA.pl(1).

       OPENSSL_ENGINES
           Specifies the directory from which dynamic engines are loaded.  See
           openssl-engine(1).

       OPENSSL_MALLOC_FD, OPENSSL_MALLOC_FAILURES
           If built with debugging, this allows memory allocation to fail.
           See OPENSSL_malloc(3).

       OPENSSL_MODULES
           Specifies the directory from which cryptographic providers are
           loaded.  Equivalently, the generic -provider-path command-line
           option may be used.

       OPENSSL_WIN32_UTF8
           If set, then UI_OpenSSL(3) returns UTF-8 encoded strings, rather
           than ones encoded in the current code page, and the openssl(1)
           program also transcodes the command-line parameters from the
           current code page to UTF-8. This environment variable is only
           checked on Microsoft Windows platforms.

       RANDFILE
           The state file for the random number generator.  This should not be
           needed in normal use.  See RAND_load_file(3).

       SSL_CERT_DIR, SSL_CERT_FILE
           Specify the default directory or file containing CA certificates.
           See SSL_CTX_load_verify_locations(3).

       TSGET
           Additional arguments for the tsget(1) command.

       OPENSSL_ia32cap, OPENSSL_sparcv9cap, OPENSSL_ppccap, OPENSSL_armcap,
       OPENSSL_s390xcap
           OpenSSL supports a number of different algorithm implementations
           for various machines and, by default, it determines which to use
           based on the processor capabilities and run time feature enquiry.
           These environment variables can be used to exert more control over
           this selection process.  See OPENSSL_ia32cap(3),
           OPENSSL_s390xcap(3).

       NO_PROXY, HTTPS_PROXY, HTTP_PROXY
           Specify a proxy hostname.  See OSSL_HTTP_parse_url(3).
