NAME¶
crypto_blkcipher_encrypt - encrypt plaintextSYNOPSIS¶
int crypto_blkcipher_encrypt(struct blkcipher_desc * desc, struct scatterlist * dst, struct scatterlist * src, unsigned int nbytes);
ARGUMENTS¶
descreference 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 occurredAUTHORS¶
