- Transposition
- A cipher which In cryptography, a transposition cipher is a method of encryption by which the positions held by units of plaintext (which are commonly characters or groups of characters) are shifted according to a regular system, so that the ciphertext constitutes a permutation of the plaintext.
- Untitled
- One example of a transposition cipher, is to reverse the order of the letters in a plaintext. So "a simpleexample" becomes "ELPMAXE ELPMIS A".
- Substitution
- Key
- A cipher which In cryptography, a substitution cipher is a method of encrypting by which units of plaintext are replaced withciphertext, according to a fixed system; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth
