Constructor Detail
AESKeySpec
- public AESKeySpec(byte[] key)
- throws java.security.InvalidKeyException
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. Method Detail
isFipsApproved
- public boolean isFipsApproved()
Description copied from interface:
AlgorithmStatus
Module identifies if the cryptographic operation (algorithm) is FIPS certified
Specified by:
isFipsApproved
in interface AlgorithmStatus

Throws:
FIPSRuntimeException
- if SelfTest.isFipsRunnable returns false. internalGetKey
- protected byte[] internalGetKey( )
key
as the key material for the AES key.The bytes that constitute the AES key are those between
key[0]
andkey[key.length - 1]
inclusive.
