151 .IX Header "DESCRIPTION"
152 \&\fISSL_get_current_cipher()\fR returns a pointer to an \s-1SSL_CIPHER\s0 object containing
153 the description of the actually used cipher of a connection established with
154 the \fBssl\fR object.
156 \&\fISSL_get_cipher()\fR and \fISSL_get_cipher_name()\fR are identical macros to obtain the
157 name of the currently used cipher. \fISSL_get_cipher_bits()\fR is a
158 macro to obtain the number of secret/algorithm bits used and
159 \&\fISSL_get_cipher_version()\fR returns the protocol name.
160 See \fISSL_CIPHER_get_name\fR\|(3) for more details.
162 .IX Header "RETURN VALUES"
163 \&\fISSL_get_current_cipher()\fR returns the cipher actually used or \s-1NULL\s0, when
164 no session has been established.
