Java has methods to compute digests over data: see the class java.security.MessageDigest. I want to store the pasword in a mysql database table in encrypted form. Again i need to decrypt whenever i need, for example during password verification I want some encryption and decryption program ...
I hope to get some help, how to deal with the 20-bit key in order to make my normal decryption, thank you very much. hello, i have got the same question, if i don not use "new SecretKeySpec(password.getBytes(), KEY_ALGORITHM);" for instead in java, how to solved this problem ...
Before using this library, you will need to set up a project in the Mastercard Developers Portal. As part of this set up, you'll receive: A public request encryption certificate (aka Client Encryption Keys) A private response decryption key (aka Mastercard Encryption Keys) Adding the Library ...
