BlockCipher
A block cipher is a data encryption algorithm that operates on blocks.
| Methods |
|---|
| void |
decrypt(byte[] bytes, int off, int len)
Decrypt a number of bytes.
|
| void |
decrypt(byte[] bytes, int off, int len)
Decrypt a number of bytes. This is done in-place, that
means the bytes are overwritten.
Parameters:
bytes - the byte array
off - the start index
len - the number of bytes to decrypt
|
| void |
encrypt(byte[] bytes, int off, int len)
Encrypt a number of bytes.
|
| void |
encrypt(byte[] bytes, int off, int len)
Encrypt a number of bytes. This is done in-place, that
means the bytes are overwritten.
Parameters:
bytes - the byte array
off - the start index
len - the number of bytes to encrypt
|
| int |
getKeyLength()
Get the length of the key in bytes.
|
| int |
getKeyLength()
Get the length of the key in bytes.
Returns:
the length of the key
|
| void |
setKey(byte[] key)
Set the encryption key used for encrypting and decrypting.
|
| void |
setKey(byte[] key)
Set the encryption key used for encrypting and decrypting.
The key needs to be 16 bytes long.
Parameters:
key - the key
