.SH "NAME"
crypto_blkcipher_encrypt_iv \- encrypt plaintext with dedicated IV
.SH "SYNOPSIS"

.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
.PP
\fInbytes\fR
.RS 4
number of bytes of the plaintext to encrypt\&.
.RE
.SH "DESCRIPTION"
.PP
Encrypt plaintext data with the use of an IV that is solely used for this cipher operation\&. Any previously set IV is not used\&.
.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\&.info is filled with the IV to be used for the current operation; 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
