Method Summary

int	cipherBlockSize() Returns the size of the blocks that can be decrypted in one call to decrypt().
void	encrypt(byte[] source, int i, byte[] dest, int j) Encrypt one block of data.
int	plainBlockSize() Returns the size of the blocks that can be encrypted in one call to encrypt().

Method Detail

plainBlockSize

public int plainBlockSize()

Returns the size of the blocks that can be encrypted in one call to encrypt().

cipherBlockSize

public int cipherBlockSize()

Returns the size of the blocks that can be decrypted in one call to decrypt().

encrypt

public void encrypt(byte[] source,
                    int i,
                    byte[] dest,
                    int j)

Encrypt one block of data. The plaintext is taken from source starting at offset i and ciphertext is written to dest, starting at offset j.

The amount of data read and written will match the values returned by plainBlockSize() and cipherBlockSize().
