Welcome fellow hacker. Spring Crypto Utils belongs to an era when configuration of java applications was done in Spring's xml files. Thank god that era is no more and we now do things in plain java.

If you are really looking for Spring Crypto Utils, it is of course still available and the stable version is in branch 1.4.
Bye, Mirko.
