public class RC2ParameterSpec extends Object implements AlgorithmParameterSpec
The parameters consist of an effective key size and optionally an 8-byte initialization vector (IV) (only in feedback mode).
This class can be used to initialize a Cipher object that
implements the RC2 algorithm.
| Constructor | Description |
|---|---|
RC2ParameterSpec(int effectiveKeyBits) |
Constructs a parameter set for RC2 from the given effective key size
(in bits).
|
RC2ParameterSpec(int effectiveKeyBits,
byte[] iv) |
Constructs a parameter set for RC2 from the given effective key size
(in bits) and an 8-byte IV.
|
RC2ParameterSpec(int effectiveKeyBits,
byte[] iv,
int offset) |
Constructs a parameter set for RC2 from the given effective key size
(in bits) and IV.
|

The bytes that constitute the IV are those between
iv[0] and iv[7] inclusive.

The IV is taken from iv, starting at
offset inclusive.
