The American Cryptogram Association (ACA) is a non-profit organization dedicated to promoting the hobby and art of cryptanalysis — that is, learning to break ciphers.
Cryptography can be more than merely an entertainment for the enjoyment of ingenuity. It engages the mind fully and can provide a healthy period of work for those unable to do much else. It can become a harmless addiction, a passion, so captivating are the efforts required in grappling with a problem. Cryptographers are diversified in every way. Hardly a trade or profession has missed representation among us. Age is not a factor; we have had members under 10 and over 90. Formal education seems totally unrelated to the curious talent.
We are banded together in an organization which represents everyone with these aims — to gain the most from a study of cryptograms, to form worth-while friendships, and to pass on the knowledge we have been able to add to the Art of Cryptography.
One way to learn what we do is to check out the Sample Issue of our bi-monthly publication: The Cryptogram. The Sample Issue shows several of the cipher types we use, and there are tutorial solutions available that show how these ciphers can be approached and solved.
