crypto_blkcipher_encrypt – encrypt plaintext
Synopsis
int crypto_blkcipher_encrypt(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 using the IV set by the caller with a preceding call of crypto_blkcipher_set_iv.
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.
Return
0 if the cipher operation was successful; < 0 if an error occurred
