AESKeySpec
public AESKeySpec(byte[] key)
throws java.security.InvalidKeyException
- Uses the bytes in
key
as the key material for the
AES key.
The bytes that constitute the AES key are those between
key[0]
and key[key.length - 1]
inclusive.
- Parameters:
key
- the buffer with the AES key material.- Throws:
java.security.InvalidKeyException
- if the given key material is not 16, 24, or 32 bytes.
AESKeySpec
public AESKeySpec(byte[] key,
int offset,
int len)
throws java.security.InvalidKeyException
- Uses the bytes in
key
, beginning at
offset
inclusive, as the key material for the AES key.
The bytes that constitute the AES key are those between
key[offset]
and key[offset+len-1]
inclusive.
- Parameters:
key
- the buffer with the AES key material.offset
- the offset in key
, where the DES key
material starts.- Throws:
java.security.InvalidKeyException
- if the given key material, starting at
offset
inclusive, is not 16, 24, or 32 bytes.
isFipsApproved
public boolean isFipsApproved()
- Description copied from interface:
AlgorithmStatus
- Module identifies if the cryptographic operation (algorithm) is FIPS certified

getKey
public byte[] getKey()
- Returns the AES key material.
- Returns:
- the AES key material.
- Throws:
