Hashing is a common technique used in cryptography to encode information quickly using typical algorithms. Generally, an algorithm is applied to a string of text, and the resulting string becomes the "hash value". This creates a "digital fingerprint" of the message, as the specific hash value is used to identify a specific message.
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.
Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία-logia, "study", respectively [1]), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [2]
Augustus the Younger, Duke of Brunswick-Lüneburg, wrote a standard book on cryptography; Ibn Wahshiyya: published several cipher alphabets that were used to encrypt magic formulas. [1] John Dee, wrote an occult book, which in fact was a cover for crypted text

The besiegers intercepted a coded letter leaving the city. Rossignol, then a 26-year-old mathematician, had a local reputation for his interest in cryptography. He quickly broke the Huguenot cipher, revealing a plea to their allies for ammunition to replenish the city's almost exhausted supplies.
The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography is a book by Simon Singh, published in 1999 by Fourth Estate and Doubleday. The Code Book describes some illustrative highlights in the history of cryptography , drawn from both of its principal branches, codes and ciphers .
