.\&quot; Set up some character translations and predefined strings.  \*(-- will
.\&quot; give an unbreakable dash, \*(PI will give pi, \*(L&quot; will give a left
.\&quot; double quote, and \*(R&quot; will give a right double quote.  \*(C+ will
.\&quot; give a nicer C++.  Capital omega is used to do unbreakable dashes and
.\&quot; therefore won't be available.  \*(C` and \*(C' expand to `' in nroff,
.\&quot; nothing in troff, for use with C&lt;&gt;.

.SH &quot;DESCRIPTION&quot;
.IX Header &quot;DESCRIPTION&quot;
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
\&amp;\fBOpenSSL_add_all_digests()\fR adds all digest algorithms to the table.
.PP
\&amp;\fBOpenSSL_add_all_algorithms()\fR adds all algorithms to the table (digests and
ciphers).
.PP
\&amp;\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 &quot;RETURN VALUES&quot;
.IX Header &quot;RETURN VALUES&quot;
None of the functions return a value.

.SH &quot;HISTORY&quot;
.IX Header &quot;HISTORY&quot;
The \fBOpenSSL_add_all_algorithms()\fR, \fBOpenSSL_add_all_ciphers()\fR,
\&amp;\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.
