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_TRACE By default the OpenSSL trace feature is disabled statically. To enable it, OpenSSL must be built with tracing support, which may be configured like this: "./config enable-trace" Unless OpenSSL tracing support is generally disabled, enable trace output of specific parts of OpenSSL libraries, by name. This output usually makes sense only if you know OpenSSL internals well. The value of this environment varialble is a comma-separated list of names, with the following available: TRACE Traces the OpenSSL trace API itself. INIT Traces OpenSSL library initialization and cleanup. TLS Traces the TLS/SSL protocol. TLS_CIPHER Traces the ciphers used by the TLS/SSL protocol. CONF Show details about provider and engine configuration. ENGINE_TABLE The function that is used by RSA, DSA (etc) code to select registered ENGINEs, cache defaults and functional references (etc), will generate debugging summaries. ENGINE_REF_COUNT Reference counts in the ENGINE structure will be monitored with a line of generated for each change. PKCS5V2 Traces PKCS#5 v2 key generation. PKCS12_KEYGEN Traces PKCS#12 key generation. PKCS12_DECRYPT Traces PKCS#12 decryption. X509V3_POLICY Generates the complete policy tree at various points during X.509 v3 policy evaluation. BN_CTX Traces BIGNUM context operations. CMP Traces CMP client and server activity. STORE Traces STORE operations. DECODER Traces decoder operations. ENCODER Traces encoder operations. REF_COUNT Traces decrementing certain ASN.1 structure references. HTTP Traces the HTTP client and server, such as messages being sent and received. 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_riscvcap 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) and OPENSSL_riscvcap(3). NO_PROXY, HTTPS_PROXY, HTTP_PROXY Specify a proxy hostname. See OSSL_HTTP_parse_url(3). QLOGDIR Specifies a QUIC qlog output directory. See openssl-qlog(7). OSSL_QFILTER Used to set a QUIC qlog filter specification. See openssl-qlog(7).
