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.
- 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).
