Java Password or String Encryption and Decryption

[@integrationspecialist]

If you see any error in decryption you can update the line (It depends on version):
From:
byte[] encryptedText = Base64.decodeBase64(encryptedString);
To:
byte[] encryptedText = Base64.decodeBase64(encryptedString.getBytes());
