方法详细资料

isNative

public static boolean isNative()

verify

public static MyCryptoStatus verify()

Verifies the availability and status of the RdRand instruction on the host.

返回:

Status of the RdRand instruction on the host.

nextBytesNative

public static int nextBytesNative(byte[] bytes,
                                  int size)

Native method fetching the specified number of bytes in the provided byte array from RdRand.

参数:

bytes - The byte array to fill with random bytes.

size - The number of random bytes to fetch.

返回:

Numeric status code returned by RdRand for the fetch operation.

nextBytes

public static void nextBytes(byte[] bytes)

Fetches random bytes from RdRand and places them into the user specified array. The number of random bytes fetched is equal to the length of the byte array.

参数:

bytes - The byte array to fill with random bytes.

sm3HashNative

public static int sm3HashNative(byte[] md,
                                byte[] inbuf,
                                int lenbufLen)

参数:

md - The output md, must be 32 bytes length

inbuf - The input buf to hash

lenbufLen - Length of input buf

返回:

Numeric status code returned by MyCrypto for the fetch operation. Caculate the SM3 hash

sm3KDFNative

public static int sm3KDFNative(byte[] outbuf,
                               int outbufLen,
                               byte[] inbuf,
                               int inbufLen)

参数:

outbuf - The output buffer of outputLen length.

outbufLen - Ouput buffer length.

inbuf - The input buffer.

inbufLen - The input buffer length.

返回:

SM3 KDF function

sm4CbcEncryptWithMacNative

public static int sm4CbcEncryptWithMacNative(byte[] encKey,
                                             byte[] macKey,
                                             byte[] iv,
                                             byte[] plaintext,
                                             int plaintextLen,
                                             byte[] ciphertext,
                                             int[] ciphertextLen)

参数:

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

macKey - [in ] mac key data, 16 bytes

iv - [in ] iv data, 16 bytes, random number

plaintext - [in ] plaintext data, plaintextLen bytes

plaintextLen - [in ] the byte length of plaintextLen data
