Crypto-gram is a
free monthly electronic newsletter published since May 1998 by
Bruce Schneier, well-known
cryptography wizard and author of "
Applied Cryptography". It features summaries,
news and
opinion pieces from the world of
cryptography and is well worth a read.
Since the URL might change and E2 hopefully will be around for a long time I suggest you do a web search for "Bruce Schneier" and "crypto-gram" if you are interested in subscribing.
