I came across an interesting post by Lewis Cunningham yesterday titled http://blogs.ittoolbox.com/oracle/guide/archives/006952.asp?rss=1 - (broken link) Cryptography in the Database. This post talks about a new book called Cryptography in the Database : The Last Line of Defense
. The book is by Kevin Kenan and although I have not seen it myself I have just ordered it from Amazon. You know me anything with database and something to do with security in the title..:-).
The book sounds very interesting and is database agnostic. The book according to Amazon also includes 3000 lines of example code. There are also some great reviews of it on Amazon. As Lewis points out there is a sample chapter on DMReview in a post titled "Managing the Cryptographic Project
Looks interesting, thanks for the link Lewis.
