.SH "DESCRIPTION"
|
|
.IX Header "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.
|
|
.IP "\fB\s-1CTLOG_FILE\s0\fR" 4
|
|
.IX Item "CTLOG_FILE"
|
|
Specifies the path to a certificate transparency log list.
|
|
See \fICTLOG_STORE_new\fR\|(3).
|
|
.IP "\fB\s-1OPENSSL\s0\fR" 4
|
|
.IX Item "OPENSSL"
|
|
Specifies the path to the \fBopenssl\fR executable. Used by
|
|
the \fBrehash\fR script (see \*(L"Script Configuration\*(R" in \fIopenssl\-rehash\fR\|(1))
|
|
and by the \fB\s-1CA\s0.pl\fR script (see \*(L"\s-1NOTES\*(R"\s0 in \s-1\fICA\s0.pl\fR\|(1)
|
|
.IP "\fB\s-1OPENSSL_CONF\s0\fR, \fB\s-1OPENSSL_CONF_INCLUDE\s0\fR" 4
|
|
.IX Item "OPENSSL_CONF, OPENSSL_CONF_INCLUDE"
|
|
Specifies the path to a configuration file and the directory for
|
|
included files.
|
|
See \fIconfig\fR\|(5).
|
|
.IP "\fB\s-1OPENSSL_CONFIG\s0\fR" 4
|
|
.IX Item "OPENSSL_CONFIG"
|
|
Specifies a configuration option and filename for the \fBreq\fR and \fBca\fR
|
|
commands invoked by the \fB\s-1CA\s0.pl\fR script.
|
|
See \s-1\fICA\s0.pl\fR\|(1).
|
|
.IP "\fB\s-1OPENSSL_ENGINES\s0\fR" 4
|
|
.IX Item "OPENSSL_ENGINES"
|
|
Specifies the directory from which dynamic engines are loaded.
|
|
See \fIopenssl\-engine\fR\|(1).
|
|
.IP "\fB\s-1OPENSSL_MALLOC_FD\s0\fR, \fB\s-1OPENSSL_MALLOC_FAILURES\s0\fR" 4
|
|
.IX Item "OPENSSL_MALLOC_FD, OPENSSL_MALLOC_FAILURES"
|
|
If built with debugging, this allows memory allocation to fail.
|
|
See \fIOPENSSL_malloc\fR\|(3).
|
|
.IP "\fB\s-1OPENSSL_MODULES\s0\fR" 4
|
|
.IX Item "OPENSSL_MODULES"
|
|
Specifies the directory from which cryptographic providers are loaded.
|
|
Equivalently, the generic \fB\-provider\-path\fR command-line option may be used.
|
|
.IP "\fB\s-1OPENSSL_WIN32_UTF8\s0\fR" 4
|
|
.IX Item "OPENSSL_WIN32_UTF8"
|
|
If set, then \fIUI_OpenSSL\fR\|(3) returns \s-1UTF\-8\s0 encoded strings, rather than
|
|
ones encoded in the current code page, and
|
|
the \fIopenssl\fR\|(1) program also transcodes the command-line parameters
|
|
from the current code page to \s-1UTF\-8.\s0
|
|
This environment variable is only checked on Microsoft Windows platforms.
|
|
.IP "\fB\s-1RANDFILE\s0\fR" 4
|
|
.IX Item "RANDFILE"
|
|
The state file for the random number generator.
|
|
This should not be needed in normal use.
|
|
See \fIRAND_load_file\fR\|(3).
|
|
.IP "\fB\s-1SSL_CERT_DIR\s0\fR, \fB\s-1SSL_CERT_FILE\s0\fR" 4
|
|
.IX Item "SSL_CERT_DIR, SSL_CERT_FILE"
|
|
Specify the default directory or file containing \s-1CA\s0 certificates.
|
|
See \fISSL_CTX_load_verify_locations\fR\|(3).
|
|
.IP "\fB\s-1TSGET\s0\fR" 4
|
|
.IX Item "TSGET"
|
|
Additional arguments for the \fItsget\fR\|(1) command.

|
|
.IX Item "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 \fIOPENSSL_ia32cap\fR\|(3), \fIOPENSSL_s390xcap\fR\|(3).

|
.IP "\fB\s-1NO_PROXY\s0\fR, \fB\s-1HTTPS_PROXY\s0\fR, \fB\s-1HTTP_PROXY\s0\fR" 4
