openssl-env - OpenSSL environment variables
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).
OPENSSL_CONF , OPENSSL_CONF_INCLUDE
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 CA .pl script. See CA .pl(1).
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).
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).
SSL_CERT_DIR , SSL_CERT_FILE
Specify the default directory or file containing CA certificates. See SSL_CTX_load_verify_locations(3).
Additional arguments for the tsget(1) command.
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).
