Finally, since SecretKey is Serializable, implementations should also override ObjectOutputStream.writeObject(java.lang.Object) to prevent keys that have been destroyed from being serialized. Keys that implement this interface return the string RAW as their encoding format (see getFormat), and return...

public SecretKeySpec(byte[] key, String algorithm)从给定的字节数组构造一个密钥。 此构造函数不检查给定的字节是否确实指定了指定算法的密钥。 例如,如果算法是DES,则此构造函数不检查key是否为8字节长,并且也不检查弱键或半弱键。 为了执行这些检查,应该使用特定于算法的密钥规范类(在这种情况下: DESKey...
You can convert the SecretKey to a byte array (byte[]), then Base64 encode that to a String. To convert back to a SecretKey, Base64 decode the String and use it in a SecretKeySpec to rebuild your original SecretKey. For Java 8 SecretKey to String: // create new key SecretKey s...
