带加密密钥的PHP加密的Java等效项

Question

I am trying to find a java equivalent for PHP crypt() function. I found it here , but the answer says nothing about crypting with a crypt key. I have a PHP website which uses md5 encryption and I have a datatable for users with their passwords encrypted like this

crypt($password, CRYPT_KEY)

with CRYPT_KEY being a constant. Now I need to use that same datatable for a project in Java. How can I use the Java digest function (or any other md5 encyption function) with a crypt key?

Answer 1

Which hashing algorithm does your combination of php-version/platform use? php's crypt() can choose from a number of algorithms as detailed here: http://php.net/manual/en/function.crypt.php

Answer 2

The commons-codec from Apache has a class Crypt that implements this functionality. As of version 1.10, it supports these algorithms:

• CRYPT_SHA512
• CRYPT_SHA256
• CRYPT_MD5
• CRYPT_STD_DES
