.\&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;.

.\&quot; If the F register is &gt;0, we'll generate index entries on stderr for
.\&quot; titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
.\&quot; entries marked with X&lt;&gt; in POD.  Of course, you'll have to process the
.\&quot; output yourself in some meaningful fashion.
.\&quot;
.\&quot; Avoid warning from groff about undefined register 'F'.

.SH &quot;DESCRIPTION&quot;
.IX Header &quot;DESCRIPTION&quot;
The \s-1RC4\s0 stream cipher for \s-1EVP.\s0
.IP &quot;\fBEVP_rc4()\fR&quot; 4
.IX Item &quot;EVP_rc4()&quot;
\&amp;\s-1RC4\s0 stream cipher. This is a variable key length cipher with a default key
length of 128 bits.
.IP &quot;\fBEVP_rc4_40()\fR&quot; 4
.IX Item &quot;EVP_rc4_40()&quot;
\&amp;\s-1RC4\s0 stream cipher with 40 bit key length.
.Sp
\&amp;\s-1WARNING:\s0 this function is obsolete. Its usage should be replaced with the
\&amp;\fBEVP_rc4()\fR and the \fBEVP_CIPHER_CTX_set_key_length()\fR functions.
.IP &quot;\fBEVP_rc4_hmac_md5()\fR&quot; 4
.IX Item &quot;EVP_rc4_hmac_md5()&quot;
Authenticated encryption with the \s-1RC4\s0 stream cipher with \s-1MD5\s0 as \s-1HMAC.\s0
.Sp
\&amp;\s-1WARNING:\s0 this is not intended for usage outside of \s-1TLS\s0 and requires calling of
some undocumented ctrl functions. These ciphers do not conform to the \s-1EVP AEAD\s0
interface.
.SH &quot;RETURN VALUES&quot;
.IX Header &quot;RETURN VALUES&quot;
These functions return an \fB\s-1EVP_CIPHER\s0\fR structure that contains the
implementation of the symmetric cipher. See \fBEVP_CIPHER_meth_new\fR\|(3) for
details of the \fB\s-1EVP_CIPHER\s0\fR structure.
