| BlockCipherMac | | public class BlockCipherMac implements Mac(Code) | | |
| Constructor Summary | |
| public | BlockCipherMac(BlockCipher cipher)
create a standard MAC based on a block cipher. | | public | BlockCipherMac(BlockCipher cipher, int macSizeInBits)
create a standard MAC based on a block cipher with the size of the
MAC been given in bits. |
| BlockCipherMac | | public BlockCipherMac(BlockCipher cipher)(Code) | | create a standard MAC based on a block cipher. This will produce an
authentication code half the length of the block size of the cipher.
Parameters:
cipher - the cipher to be used as the basis of the MAC generation. |
| BlockCipherMac | | public BlockCipherMac(BlockCipher cipher, int macSizeInBits)(Code) | | create a standard MAC based on a block cipher with the size of the
MAC been given in bits.
Note: the size of the MAC must be at least 16 bits (FIPS Publication 113),
and in general should be less than the size of the block cipher as it reduces
the chance of an exhaustive attack (see Handbook of Applied Cryptography).
Parameters:
cipher - the cipher to be used as the basis of the MAC generation.
Parameters:
macSizeInBits - the size of the MAC in bits, must be a multiple of 8. |
