.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
OpenSSL keeps an internal table of digest algorithms and ciphers. It uses
this table to lookup ciphers via functions such as \fBEVP_get_cipher_byname()\fR.
.PP
\&\fBOpenSSL_add_all_digests()\fR adds all digest algorithms to the table.
.PP
\&\fBOpenSSL_add_all_algorithms()\fR adds all algorithms to the table (digests and
ciphers).
.PP
\&\fBOpenSSL_add_all_ciphers()\fR adds all encryption algorithms to the table including
password based encryption algorithms.
.PP
In versions prior to 1.1.0 \fBEVP_cleanup()\fR removed all ciphers and digests from
the table. It no longer has any effect in OpenSSL 1.1.0.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
None of the functions return a value.

.IX Header "HISTORY"
The \fBOpenSSL_add_all_algorithms()\fR, \fBOpenSSL_add_all_ciphers()\fR,
\&\fBOpenSSL_add_all_digests()\fR, and \fBEVP_cleanup()\fR, functions
were deprecated in OpenSSL 1.1.0 by \fBOPENSSL_init_crypto()\fR and should
not be used.
