.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fISSL_SESSION_get0_cipher()\fR retrieves the cipher that was used by the
connection when the session was created, or \s-1NULL\s0 if it cannot be determined.
.PP
The value returned is a pointer to an object maintained within \fBs\fR and
should not be released.
.PP
\&\fISSL_SESSION_set_cipher()\fR can be used to set the ciphersuite associated with the
\&\s-1SSL_SESSION \s0\fBs\fR to \fBcipher\fR. For example, this could be used to set up a
session based \s-1PSK \s0(see \fISSL_CTX_set_psk_use_session_callback\fR\|(3)).
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fISSL_SESSION_get0_cipher()\fR returns the \s-1SSL_CIPHER\s0 associated with the \s-1SSL_SESSION\s0
or \s-1NULL\s0 if it cannot be determined.
.PP
\&\fISSL_SESSION_set_cipher()\fR returns 1 on success or 0 on failure.
