.SH "ARGUMENTS"
.PP
\fIdesc\fR
.RS 4
reference to the block cipher handle with meta data
.RE
.PP
\fIdst\fR
.RS 4
scatter/gather list that is filled by the cipher operation with the ciphertext
.RE
.PP
\fIsrc\fR
.RS 4
scatter/gather list that holds the plaintext
.RE

.SH "DESCRIPTION"
.PP
Encrypt plaintext data using the IV set by the caller with a preceding call of crypto_blkcipher_set_iv\&.
.PP
The blkcipher_desc data structure must be filled by the caller and can reside on the stack\&. The caller must fill desc as follows: desc\&.tfm is filled with the block cipher handle; desc\&.flags is filled with either CRYPTO_TFM_REQ_MAY_SLEEP or 0\&.
.SH "RETURN"
.PP
0 if the cipher operation was successful; < 0 if an error occurred
