Deprecated.
use BlowfishCBC(byte[], int, int, byte[], int) instead
|
BlowfishCBC(byte[] key,
int nOfs,
int nLen)
Constructor, uses a zero CBC IV.
|
BlowfishCBC(byte[] key,
int nOfs,
int nLen,
byte[] initCBCIV,
int nIVOfs)
Constructor to define the CBC IV.
|
BlowfishCBC(byte[] key,
int nOfs,
int nLen,
long lInitCBCIV)
Constructor to define the CBC IV.
|
BlowfishCBC(byte[] key,
long lInitCBCIV)

|
int |
decrypt(byte[] inBuf,
int nInPos,
byte[] outBuf,
int nOutPos,

byte[] outBuf,
int nOutPos,
int nLen)
Encrypts a byte buffer to another buffer, extra misaligned data
will not be processed.
|

getCBCIV()
Gets the current CBC IV.
|
void |
getCBCIV(byte[] dest)
Deprecated.
use getCBCIV(byte[], int) instead
|
void |
getCBCIV(byte[] dest,
int nOfs)
Gets a copy of the current CBC IV.
|
void |
reset(byte[] key,
int offset,
int length)
Reset the Encryptor/Decryptor using a specific key.
|
void |
setCBCIV(byte[] newCBCIV)
Deprecated.
use setCBCIV(byte[], int) instead
|
void |
setCBCIV(byte[] newCBCIV,
int nOfs)
Sets the current CBC IV (for cipher resets).
|
void |
setCBCIV(long lNewCBCIV)
Sets the current CBC IV (for cipher resets).
