I am using PBE encryption to encrypt and decrypt some text on an Android application but I get the BadPaddingException: with the "pad block corrupted" message when I use the wrong private key to decrypt the text. My question, since I am not well versed with encryption in Java, is if this is the normal behavior of the encryption API, because I need to do some logic in the case when the wrong key is entered, but I do not know the private key, nor do I store it anywhere (storing just the encrypted and decrypted check text).

Thanks, Mihai
