Class javax.crypto.spec.IvParameterSpec
java.lang.Object
|
+----javax.crypto.spec.IvParameterSpec
- public class IvParameterSpec
- extends Object
- implements AlgorithmParameterSpec
This class specifies an initialisation vector (IV). IVs are used by
ciphers in feedback mode, e.g., DES in CBC mode.
- See Also:
- AlgorithmParameterSpec
-
ident
-
-
IvParameterSpec(byte[])
- Uses the bytes in iv as the IV.
-
IvParameterSpec(byte[], int, int)
- Uses the first len bytes in iv, beginning at offset, as the IV.
-
getIV()
- Returns the initialisation vector (IV).
ident
public static final String ident
IvParameterSpec
public IvParameterSpec(byte iv[])
- Uses the bytes in iv as the IV.
- Parameters:
- iv - the buffer with the IV
IvParameterSpec
public IvParameterSpec(byte iv[],
int offset,
int len)
- Uses the first len bytes in iv, beginning at offset, as the IV.
- Parameters:
- iv - the buffer with the IV
- offset - the offset in iv, where the IV starts
- len - the number of IV bytes
getIV
public byte[] getIV()
- Returns the initialisation vector (IV).
- Returns:
- the initialisation vector (IV)
