A description of how this cipher works instructive since it relatively easy and requires only pencil paper with easily remembered keyword. Using normal text as keyword is an aid to the cryptanalysis however since can be decrypted parallel with plaintext message. Since there was not an even number of letters message it padded with spare X. Scholars had already analyzed the frequency of word and letters in Koran so adDuraihim compared those frequencies to ciphertext decode message. Attack models edit Ciphertextonly the cryptanalyst has access collection of ciphertexts or codetexts Knownplaintext attacker set which knows corresponding Chosenplaintext can obtain arbitrary plaintexts his choosing Batch where chooses all before any them are encrypted

Note the ciphertext above has some errors in it see this comment for more correct version. The major eras which have shaped cryptography are listed below.
