How to create a hash like apache htpasswd using java

Question

I use "force MD5 password encryption" in htpasswd to generate a hash, for example, "123", I get:

use htpasswd: 123 => $ apr1 $ kaTbKaLO $ ewJXRZAKpjaxK4thy2jOp /

use the MD5 digest: 123 => 202cb962ac59075b964b07152d234b70

please tell me how can I generate a hash, for example apache htpasswd using java Thank you.

Answer 1

Passwords in Apache.htpasswd files are encoded using salt . If you want to generate these passwords using Java, you will need to do the same. This site contains an explanation of the salt / hash algorithm used for Apache.htpasswd files; I am looking for an actual algorithm that you could use, and edit my answer after I find it.

EDIT : it looks like this was asked earlier, right here on SO:

Htpasswd programming

Here's the documentation from Apache, as well as their source code:

Answer 4

Md5Crypt is what you are looking for. It implements Apache htpasswd algorithms.

Apache-specific algorithm using a redesigned ( 1000 times ) MD5 digest of various combinations of random 32-bit salt and password .

import org.apache.commons.codec.digest.Md5Crypt;
...
String enPasswd = Md5Crypt.md5Crypt("your plain password".getBytes());
String htpasswdContent = "your username:" + enPasswd;
