openssl-env - OpenSSL environment variables


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.

Specifies the path to a certificate transparency log list. See CTLOG_STORE_new(3).
Specifies the path to the openssl executable. Used by the rehash script (see "Script Configuration" in openssl-rehash(1)) and by the script (see "NOTES" in
Specifies the path to a configuration file and the directory for included files. See config(5).
Specifies a configuration option and filename for the req and ca commands invoked by the script. See
Specifies the directory from which dynamic engines are loaded. See openssl-engine(1).
If built with debugging, this allows memory allocation to fail. See OPENSSL_malloc(3).
Specifies the directory from which cryptographic providers are loaded. Equivalently, the generic -provider-path command-line option may be used.
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.
The state file for the random number generator. This should not be needed in normal use. See RAND_load_file(3).
Specify the default directory or file containing CA certificates. See SSL_CTX_load_verify_locations(3).
Additional arguments for the tsget(1) command.
