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 and 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. | 
| Modifier and Type | Method and Description | 
|---|---|
| boolean | equals(Object obj)Tests for equality between the specified object and this
 object. | 
| int | getEffectiveKeyBits()Returns the effective key size in bits. | 
| byte[] | getIV()Returns the IV or null if this parameter set does not contain an IV. | 
| int | hashCode()Calculates a hash code value for the object. |

effectiveKeyBits - the effective key size in bits.public RC2ParameterSpec(int effectiveKeyBits,

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

 the buffer are copied to protect against subsequent modification.IllegalArgumentException - if iv is null.public RC2ParameterSpec(int effectiveKeyBits,

 The IV is taken from iv, starting at
 offset inclusive.
 The bytes that constitute the IV are those between
 iv[offset] and iv[offset+7] inclusive.
