	u32 `mask)`;

Arguments

alg_name: is the cra_name / name or cra_driver_name / driver name of the blkcipher cipher
type: specifies the type of the cipher
mask: specifies the mask for the cipher

Description

Allocate a cipher handle for a block cipher. The returned struct crypto_blkcipher is the cipher handle that is required for any subsequent API invocation for that block cipher.

Return
