java.lang.Object | +--javax.crypto.spec.RC2ParameterSpec
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 Summary | |
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 IV is taken from iv , starting at offset . |
Method Summary | |
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. |
