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.
