CRYPTO_BLKCIPHER_ENC(9) Programming Interface CRYPTO_BLKCIPHER_ENC(9)

NAME

crypto_blkcipher_encrypt_iv - encrypt plaintext with dedicated IV

SYNOPSIS

int crypto_blkcipher_encrypt_iv(struct blkcipher_desc * desc, struct scatterlist * dst, struct scatterlist * src, unsigned int nbytes);

ARGUMENTS

desc

reference to the block cipher handle with meta data

dst

scatter/gather list that is filled by the cipher operation with the ciphertext

src

scatter/gather list that holds the plaintext

nbytes

number of bytes of the plaintext to encrypt.

DESCRIPTION

Encrypt plaintext data with the use of an IV that is solely used for this cipher operation. Any previously set IV is not used.

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.

RETURN

0 if the cipher operation was successful; < 0 if an error occurred
