方法详细资料

sm3Hash

public static byte[] sm3Hash(byte[] inbuf)

参数:

inbuf - The input buf to hash

返回:

Hash and Throw exception. Caculate the SM3 hash

sm3KDF

public static byte[] sm3KDF(byte[] inbuf,
                            int outbufLen)

参数:

outbufLen - Ouput buffer length.

inbuf - The input buffer.

返回:

output buffer with length outbufLen and Throw exception. SM3 KDF function

sm4CbcEncryptWithMac

public static byte[] sm4CbcEncryptWithMac(byte[] encKey,
                                          byte[] macKey,
                                          byte[] plaintext)

参数:

encKey - [in ] encryption key data, 16 bytes.

macKey - [in ] mac key data, 16 bytes

plaintext - [in ] plaintext data, plaintextLen byte

返回:

The ciphertext stream. sm4 cbc encrypt wiht pkcs5 padding. generate random number inside

sm4CbcEncryptWithMac

public static byte[] sm4CbcEncryptWithMac(byte[] encKey,
                                          byte[] macKey,
                                          byte[] iv,
                                          byte[] plaintext)

参数:

encKey - [in ] encryption key data, 16 bytes.

macKey - [in ] mac key data, 16 bytes

iv - [in ] IV, 16 bytes.

plaintext - [in ] plaintext data, plaintextLen byte

返回:

The ciphertext stream. sm4 cbc encrypt wiht pkcs5 padding. generate random number outside

sm4CbcDecryptWithMac

public static byte[] sm4CbcDecryptWithMac(byte[] encKey,
                                          byte[] macKey,
                                          byte[] ciphertext)

参数:

encKey - [in ] encryption key data, 16 bytes.

macKey - [in ] mac key data, 16 bytes

ciphertext - [in] ciphertext data, ciphertextLen bytes, iv || ciphertext with mac

返回:

Throw exceptions. sm4 cbc decrypt wiht pkcs5 padding.
