Secure Java apps on Linux using MD5 crypt

You know probably the good quality of IBM's articles. 2 days ago, IBM has published a new article in the "developerWorks" corner written by Vladimir Silva. In this article, "Secure Java apps on Linux using MD5 crypt", he described the GNU extensions to the crypt() system call and provided an implementation of MD5 crypt for use with Java applications.

First, he told about some weakness of the old crypt function and then presented the MD5 crypt GNU-extension followed by the MD5 crypt algorithm and a bash script for testing against a local Linux registry (/etc/shadow).

There is a link at the end of the article to the Java implementation of the MD5 crypt.

It is a good article. I really recommend it for your free time.
