Cryptology is the study of both cryptography, the use of messages concealed by codes or ciphers, and cryptanalysis, or the breaking of coded messages. It is nearly as old as civilization itself, although ciphers and codes prior to the late medieval period in western Europe tended to be extremely simple by today's standards.
WebRainbow table - Wikipedia Rainbow table 20 languages Talk Read Edit View history Tools A rainbow table is a precomputed table for caching the outputs of a cryptographic hash function, usually for cracking password hashes. Passwords are typically stored not in plain text form, but as hash values. WebFixed tables are normally used, as in the Data Encryption Standard (DES), but in some ciphers the tables are generated dynamically from the key (e.g. the Blowfish and the Twofish encryption algorithms). Example [ edit] One good example of a fixed table is the S-box from DES (S 5 ), mapping 6-bit input into a 4-bit output:
Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively ), is the practice and study of techniques for secure communication in the presence of adversarial behavior.
