1. A character [0] which, standing by itself, expresses nothing, but when placed at the right hand of a whole number, increases its value tenfold.2. One who, or that which, has no weight or influence.3. A character in general, as a figure or letter.4. A combination or interweaving of letters, as the initials of a name; a device; a monogram; as, a painter's cipher, an engraver's cipher, etc.5. The cut represents the initials N.6. A private alphabet, system of characters, or other mode of writing, contrived for the safe transmission of secrets; also, a writing in such characters.7. Of the nature of a cipher; of no weight or influence.8. To use figures in a mathematical process; to do sums in arithmetic.9. To write in occult characters.10. To get by ciphering; as, to cipher out the answer.11. To decipher.12. To designate by characters. a message written in a secret code a secret method of writing a person of no influence.13. a message written in a secret code. . a mathematical element that when added to another number yields the same number. . a quantity of no importance; "it looked like nothing I had ever seen before"; "reduced to nil all the work we had done"; "we racked up a pathetic goose egg"; "it was all for naught"; "I didn't hear zilch about it". . a person of no influence. . a secret method of writing. . convert ordinary language into code; "We should encode the message for security reasons". . make a mathematical calculation or computation.14. An algorithm or system for data encryption Examples are DES, IDEA, RC4, etc .15. An algorithm or system for data encryption Examples are DES, IDEA, RC4, etc See: SSL/TLS Encryption.16. An encryption.17. The multics commands encode and decode implement a powerful file-encryption facility that was shipped with the system for years, starting in the early 1970s The code, contriubted by a Multician with considerable expertise in cryptography, consists of a PL/I wrapper and an assembly language guts The algorithm is some kind of Feistel cipher, similar to IBM's Lucifer algorithm, "but not the same" according to the author It was probably illegal to ship these commands internationally, but nobody realized it at the time .18. An encryption-decryption algorithm .19. A method or system of transforming text in order to conceal its meaning In particular, a cryptosystem in which the cryptographic treatment is applied to plaintext elements that either have no meaning in themselves , or are treated without regard to their meaning .20. Ciphers are codes for writing secret messages Two simple types are shift ciphers and affine ciphers .21. Procedure that transforms data between plaintext and ciphertext; a crypto algorithm .22. A system of encryption .23. An encryption algorithm .24. Any encryption algorithm Ciphers can be classified according to whether they are symmetric or asymmetric algorithms . . a method that encrypts or disguises text Ciphers replace the message letters with other letters, numbers or symbols, as in substitution, or move around the individual letters of the plaintext, as in transposition – or a combination of both .25. A mathematical algorithm used to perform encryption and decryption .26. Dr Whewell's riddle is- “A headless man had a letter to write, He who read it had lost his sight; The dumb repeated it word for word, And deaf was the man who listened and heard Circe A sorceress She lived in the island of Ææa When Ulysses landed there, Circë turned his companions into swine, but Ulysses resisted this metamorphose by virtue of a herb called moly, given him by Mercury “Who knows not Circe, The daughter of the Sun, whose charmëd cup Whoever tasted lost his upright shape, And downward fell into a grovelling swine?” Milton: Comus, 50- 53 Circle of Ulloa A white rainbow or luminous ring sometimes seen in Alpine regions opposite the sun in foggy weather .27. An algorithm for reversible transformation of data .28. An encryption - decryption algorithm .29. A disguising transformation of a message without using chunking, such as a simple substitution cipher .30. In Cryptographic Support, data that is unintelligible to all except those who have the key to decode it to plaintext .31. A system producing non-hidden messages which deals with individual letters or symbols as units of encryption instead of words or phrases The ciphertext has a direct relationship to the plaintext message .32. Some method to change a message into a non readable format letter by letter .33. A term for data which has been encrypted .34. Any encryption algorithm Ciphers can be classified according to whether they are symmetric or public key algorithms, and by whether they operate on their data as a stream or divided into blocks .35. A means of concealing a message The letters of the message are substituted or transposed for other letters, letter pairs, or polygrams Origin: Arabic: Sifr: Nothing.36. Code used to encrypt information .37. Key to a secret, as in a geometric secret, for example .
