Could someone point me in the direction of a crypt(3) library for java? One that generates results similar to PHP. e.g.

james => $1$uAjE75CY$XVIp.DpCuwQTG60h.r5er/

Thanks

Update:

The password above is separated by $. The 1 represents MD5 (variation). The next token represents the salt used for the hash and the last token represents the MD5 hash. This hash is a variation from MD5 algorithm.

Try this one,

https://github.com/jonabbey/Ganymede/blob/master/src/ganymede/arlut/csd/crypto/MD5Crypt.java

I was able to use it to compare password generated by PHP crypt.

Please notice that this class uses its own MD5 class.

yes, found all those but they are not generating passwords similar to that of php crypt().
@James Is it a requirement that the generated passwords (Java, PHP) are the same?
You are aware that most crypt-implementation needs a salt?
