Enclosing class:

SecretKeyCipher

public static final class SecretKeyCipher.CipherSpec

extends Object

CipherSpec is a wrapper for metadata about a Cipher specification. This includes:

• an algorithm short name (e.g. "DES", "DESede", "Blowfish")
• a cipher specification including it's algoritm name, blocking type, and padding type (e.g. "DES/CBC/PKCS5Padding")
• the key size supported by the SecretKeyCipher, which may be only a subset of the key sizes supported by the general JCE cipher instance.

Constructor Summary

SecretKeyCipher.CipherSpec(String algorithm, String cipherSpec, int keySize)
Create a new CipherSpec.

Method Summary

String	getAlgorithm() Get the cipher algorithm.
String	getCipherSpec() Get the cipher specification as a String.
int	getKeySize() Get the supported cipher key size.
int	hashCode() Override hashcode so that CipherSpec are hashed by algorithm.
