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