\&\fIOpenSSL_add_ssl_algorithms()\fR and \fISSLeay_add_ssl_algorithms()\fR are synonyms

.SH "NOTES"
|
|
.IX Header "NOTES"
|
|
\&\fISSL_library_init()\fR must be called before any other action takes place.

.SH "WARNING"
|
|
.IX Header "WARNING"
|
|
\&\fISSL_library_init()\fR only registers ciphers. Another important initialization
|
|
is the seeding of the \s-1PRNG\s0 (Pseudo Random Number Generator), which has to
|
|
be performed separately.
|
|
.SH "EXAMPLES"
|
|
.IX Header "EXAMPLES"
|
|
A typical \s-1TLS/SSL\s0 application will start with the library initialization,
|
|
will provide readable error messages and will seed the \s-1PRNG\s0.
