an Encryption Algorithm can utilize the following transformations:
- substitution cipher - substituting every occurrence of a symbol/group-of-bits with another symbol/group-of-bits
- permutation/transposition cipher - rearranging a sequence of symbols/bits to some other pseudorandom sequence
Substitution Cipher Examples
- ROT13 or ROT-13 - is a simple letter substitution cipher that replaces a letter with the 13th letter after it, in the alphabet
Permutation Cipher Examples
- IONO yet
