When I have a lot of values in my project that I want to encrypt, it becomes a tedious task to encrypt values from CLI one by one. Therefore I'd like to contribute to this project by adding file encryption capabilities from Command Line. I would like to sync on the requirements though.

Hey I am using your patch so I can use SHA512 JDK 8 in Jasypt. I found an issue though.

Using an old PBE like this...

public static final StandardPBEStringEncryptor ENCRYPTOR = new StandardPBEStringEncryptor();
static {
ENCRYPTOR.setAlgorithm("PBEWithMD5AndDES");
ENCRYPTOR.setPassword(PASSWORD);
}

The current string is "kVTHVfAVDJ0vjqQimc3UsQ==" and it decrypts fine with Jasypt 1.9.2. But the same with your patch fails here...

if (ivGenerator.includePlainIVInEncryptionResults()) {

                // Extracting the IV
                iv = Arrays.copyOfRange(encryptedMessageKernel, 0, IVSizeBytes / 8);
                finalEncryptedMessage = Arrays.copyOfRange(encryptedMessageKernel, iv.length, encryptedMessageKernel.length);

                if (LOGGER.isDebugEnabled())
                        LOGGER.debug("Extracted IV: {}", Arrays.toString(iv));
            }

It I reencrypt my string using your library the string is a lot longer than it was before. Any help on why the old conversion is now broken?
