decrypt

byte[] decrypt(byte[] encrypted,
               char[] password)
        throws GeneralSecurityException

Decrypts encrypted bytes, using the given password as decryption key.

The encrypted data must contain enough information about the encryption algorithm used so that it can be decrypted at all.

If the password is wrong, the method may return wrongly decrypted data. If decryption fails, it may return null or throw a GeneralSecurityException.

The caller is responsible for eventually clearing the password and the decrypted data returned.

Parameters:

encrypted - data to decrypt

password - decryption key

Returns:

decrypted data, possibly null if decryption failed

Throws:

GeneralSecurityException - may be thrown if decryption failed
