Classical cryptography is the name given to the ciphers used through
history before computers became commonplace. These ciphers are commonly called
"pen and paper" ciphers because they were targeting the complexity to be
performed by a normal person with only a pen and some paper.
Common classical ciphers include
- Caesar cipher
- Vigenere cipher
- Substitution cipher
- Transposition cipher
- Bifid and trifid ciphers
As being resistant to computers was not a goal, all of the classical
ciphers provide almost no security today.
