In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver … See more Simple Substitution of single letters separately—simple substitution—can be demonstrated by writing out the alphabet in some order to represent the substitution. This is … See more • Sherlock Holmes breaks a substitution cipher in "The Adventure of the Dancing Men". There, the cipher remained undeciphered for years if not decades; not due to its difficulty, but because no one suspected it to be a code, instead considering it … See more Substitution ciphers as discussed above, especially the older pencil-and-paper hand ciphers, are no longer in serious use.
