166 the \fBssl\fR object.
167 .PP
168 \&\fISSL_get_cipher()\fR and \fISSL_get_cipher_name()\fR are identical macros to obtain the
169 name of the currently used cipher. \fISSL_get_cipher_bits()\fR is a
170 macro to obtain the number of secret/algorithm bits used and
171 \&\fISSL_get_cipher_version()\fR returns the protocol name.
172 See \fISSL_CIPHER_get_name\fR\|(3) for more details.
173 .SH "RETURN VALUES"
174 .IX Header "RETURN VALUES"
175 \&\fISSL_get_current_cipher()\fR returns the cipher actually used or \s-1NULL\s0, when
