David Kahn notes in The Codebreakers that modern cryptology originated among the Arabs, the first people to systematically document cryptanalytic methods. [15] Al-Khalil (717–786) wrote the Book of Cryptographic Messages, which contains the first use of permutations and combinations to list all possible Arabic words with and without vowels. [16]
Historically, various forms of encryption have been used to aid in cryptography. Early encryption techniques were often used in military messaging. Since then, new techniques have emerged and become commonplace in all areas of modern computing. [1] Modern encryption schemes use the concepts of public-key and symmetric-key. [1]

A third class of information theory codes are cryptographic algorithms (both codes and ciphers). Concepts, methods and results from coding theory and information theory are widely used in cryptography and cryptanalysis, such as the unit ban. [citation needed]
The following outline is provided as an overview of and topical guide to cryptography: Cryptography (or cryptology) – practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and engineering. Applications of cryptography include ATM cards, computer passwords, and electronic ...
In cryptography, a zero-knowledge proof is a protocol in which one party (the prover) can convince another party (the verifier) that some given statement is true, without conveying to the verifier any information beyond the mere fact of that statement's truth. [1]
It is one of the foundational treatments (arguably the foundational treatment) of modern cryptography. [2] His work has been described as a "turning point, and marked the closure of classical cryptography and the beginning of modern cryptography." [3] It has also been described as turning cryptography from an "art to a science". [4]
1989 – Quantum cryptography experimentally demonstrated in a proof-of-the-principle experiment by Charles Bennett et al. 1991 – Phil Zimmermann releases the public key encryption program PGP along with its source code, which quickly appears on the Internet. 1994 – Bruce Schneier's Applied Cryptography is published.
