151\&\fIBIO_f_cipher()\fR returns the cipher \s-1BIO\s0 method. This is a filter
152\&\s-1BIO\s0 that encrypts any data written through it, and decrypts any data
153read from it. It is a \s-1BIO\s0 wrapper for the cipher routines
154\&\fIEVP_CipherInit()\fR, \fIEVP_CipherUpdate()\fR and \fIEVP_CipherFinal()\fR.
155.PP
156Cipher BIOs do not support \fIBIO_gets()\fR or \fIBIO_puts()\fR.
157.PP
158\&\fIBIO_flush()\fR on an encryption \s-1BIO\s0 that is being written through is
159used to signal that no more data is to be encrypted: this is used
160to flush and possibly pad the final block through the \s-1BIO\s0.
161.PP
162\&\fIBIO_set_cipher()\fR sets the cipher of \s-1BIO\s0 \fBb\fR to \fBcipher\fR using key \fBkey\fR
163and \s-1IV\s0 \fBiv\fR. \fBenc\fR should be set to 1 for encryption and zero for
164decryption.
