Type 7 Cipher, also known as Cisco Type 7 Encryption, is a method commonly used by Cisco networking devices to obfuscate sensitive information such as passwords in configuration files. While it's referred to as encryption, Type 7 is actually a weak form of encoding designed to obscure passwords rather than securely encrypting them.

The Vigenère Cipher is a method of encrypting alphabetic text where each letter of the plaintext is encoded with a different Caesar Cipher, whose increment is determined by the corresponding letter of another text, the key.

Atbash Cipher is a substitution cipher with a specific key where the letters of the alphabet are reversed. I.e. all 'A's are replaced with 'Z's, all 'B's are replaced with 'Y's, and so on. It was originally used for the Hebrew alphabet, but can be used for any alphabet.

Beaufort Cipher, is a polyalphabetic substitution cipher that is similar to the Vigenère cipher, except that it enciphers characters in a slightly different manner.
