Copiale cipher — The Copiale cipher is an encrypted manuscript consisting of 75,000 handwritten characters filling 105 pages in a bound volume.[1] It is thought to date to between 1760 and 1780.[2] It was first examined at the German Academy of Sciences at Berlin … Wikipedia
Beale ciphers — The Beale ciphers are a set of three ciphertexts, one of which allegedly states the location of a buried treasure of gold and silver estimated to be worth over 30 million US dollars in the present time. The other two ciphertexts allegedly… … Wikipedia
Ciphertext indistinguishability — is a property of many encryption schemes. Intuitively, if a cryptosystem possesses the property of indistinguishability, then an adversary will be unable to distinguish pairs of ciphertexts based on the message they encrypt. The property of… … Wikipedia
