The American Cryptogram Association (ACA) is an American non-profit organization devoted to the hobby of cryptography, with an emphasis on types of codes, ciphers, and cryptograms that can be solved either with pencil and paper, or with computers, but not computer-only systems.
History
The ACA was formed on September 1, 1930.
Since some of its members had belonged to the “National Puzzlers' League”, some of the NPL terminology ("nom," "Krewe," etc.) is also used in the ACA.[http://www.cryptogram.org/about-the-aca/history History ACA]/
Publications and activities
The association has a collection of books and articles on cryptography and related subjects in the library at Kent State University.
An annual convention takes place in late August or early September. Recent conventions have been held in Bletchley Park and Fort Lauderdale, Florida.
There is also a regular journal called “The Cryptogram”, which first appeared in February, 1932, and has grown to a 28-page bimonthly periodical which includes articles and challenge ciphers.
