Selecting the Best AES Block Cipher Mode (AES-GCM VS AES-CBC)
The SM4 cipher has a key size and a block size of 128 bits each. Encryption or decryption of one block of data is composed of 32 rounds. A non-linear key schedule is used to produce the round keys and the decryption uses the same round keys as for encryption, except that they are in reversed order. The length of encryption keys is 128 bits, represented as , in which is a 32-bit word. The round key… Webb12 apr. 2024 · 定义为： enum {sm4}BulkCipherAlgorithm CipherType 表示密码算法的类型。 定义为： enum { block } CipherType; key_material_length 表示密钥材料的长度。 … WebbSearch Tricks.
