Cryptography frequency analysis
WebFrequency analysis is used for breaking substitution ciphers. The general idea is to find the popular letters in the ciphertext and try to replace them by the common letters in the used language. The attacker usually checks some possibilities and makes some substitutions of letters in ciphertext. He looks for possible appearing words and based ...
