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).
