You need to quickly compute hashes from Strings (for example in order to safely store passwords into a database) ?

Well, just have a look a my project named hashutils

It simply provides one utiliy class that exposes simple methods to compute hashes from Strings using the following algorithms :

• MD5
• sha1
• sha256
• sha512

hashutils is hosted in our Maven2 repository.

You can download

• the library itself
• source code as a jar archive
• javadoc as a jar archive

Simply head you way there and help yourself.

An explanation could be that Eclipse fails to claim memory that is not really used by the system, but simply cached.

A solution is to flush cache before launching Eclipse by issuing the following command (as root) in a terminal :

sync; echo 3 > /proc/sys/vm/drop_caches

Hope it helps
