 org.bouncycastle.crypto.macs.CBCBlockCipherMac
| CBCBlockCipherMac | | public class CBCBlockCipherMac implements Mac(Code) | | standard CBC Block Cipher MAC - if no padding is specified the default of
pad of zeroes is used.
|
| CBCBlockCipherMac | | public CBCBlockCipherMac(BlockCipher cipher)(Code) | | create a standard MAC based on a CBC 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. |
| CBCBlockCipherMac | | public CBCBlockCipherMac(BlockCipher cipher, BlockCipherPadding padding)(Code) | | create a standard MAC based on a CBC 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.
Parameters:
padding - the padding to be used to complete the last block. |
| CBCBlockCipherMac | | public CBCBlockCipherMac(BlockCipher cipher, int macSizeInBits)(Code) | | create a standard MAC based on a block cipher with the size of the
MAC been given in bits. This class uses CBC mode as the basis for the
MAC generation.
Note: the size of the MAC must be at least 24 bits (FIPS Publication 81),
or 16 bits if being used as a data authenticator (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. |
| CBCBlockCipherMac | | public CBCBlockCipherMac(BlockCipher cipher, int macSizeInBits, BlockCipherPadding padding)(Code) | | create a standard MAC based on a block cipher with the size of the
MAC been given in bits. This class uses CBC mode as the basis for the
MAC generation.
Note: the size of the MAC must be at least 24 bits (FIPS Publication 81),
or 16 bits if being used as a data authenticator (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.
Parameters:
padding - the padding to be used to complete the last block. |
