Declassified NSA Newsletters

Posted on by

Through a 2010 FOIA request (yes, it took that long), we have copies of the NSA’s KRYPTOS Society Newsletter, “Tales of the Krypt,” from 1994 to 2003.

There are many interesting things in the 800 pages of newsletter. There are many redactions. And a 1994 review of Applied Cryptography by redacted:

Applied Cryptography, for those who don’t read the internet news, is a book written by Bruce Schneier last year. According to the jacket, Schneier is a data security expert with a master’s degree in computer science. According to his followers, he is a hero who has finally brought together the loose threads of cryptography for the general public to understand.

The ACLU says the bureau should come clean about what its Electronic Device Analysis Unit (EDAU) is using “to unlock and decrypt information that is otherwise securely stored on cell phones.” The group filed a Freedom of Information Act lawsuit Monday in a San Francisco federal court. “We’re demanding the government release records concerning any policies applicable to the EDAU, its technological capabilities to unlock or access electronic devices, and its requests for, purchases of, or uses of software that could enable it to bypass encryption,” the ACLU says in a news release. The suit is the latest offensive in what some call the Crypto Wars — an ongoing legal and policy struggle over […]
