.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBSSL_get_current_cipher()\fR returns a pointer to an \s-1SSL_CIPHER\s0 object containing
the description of the actually used cipher of a connection established with
the \fBssl\fR object.
.PP
\&\fBSSL_get_cipher()\fR and \fBSSL_get_cipher_name()\fR are identical macros to obtain the
name of the currently used cipher. \fBSSL_get_cipher_bits()\fR is a
macro to obtain the number of secret/algorithm bits used and 
\&\fBSSL_get_cipher_version()\fR returns the protocol name.
See \fBSSL_CIPHER_get_name\fR\|(3) for more details.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBSSL_get_current_cipher()\fR returns the cipher actually used or \s-1NULL,\s0 when
no session has been established.
