TEA Encrypt & Decrypt

Key

TEA (Tiny Encryption Algorithm) is a block cipher notable for its simplicity of description and implementation, typically a few lines of code. It was designed by David Wheeler and Roger Needham of the Cambridge Computer Laboratory; it was first presented at the Fast Software Encryption workshop in Leuven in 1994, and first published in the proceedings of that workshop.

TEA operates on two 32-bit unsigned integers (could be derived from a 64-bit data block) and uses a 128-bit key. It has a Feistel structure with a suggested 64 rounds, typically implemented in pairs termed cycles. It has an extremely simple key schedule, mixing all of the key material in exactly the same way for each cycle.

Braille Cipher

Braille Cipher is a substitution cipher, it could encoding and substituting the letters in a message into "Braille" characters.
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.
