CSLSDS / bellaso
The Bellaso cipher is a method of encrypting alphabetic text by using a series of interwoven Caesar ciphers, based on the letters of a keyword. It employs a form of [polyalphabetic substitution] (https://en.wikipedia.org/wiki/Polyalphabetic_cipher).

peterstefanov / VigenereAstra
Astra implementation of Vigenere Auto Encipherment. The Vigenre cipher is a method of encrypting alphabetic text by using a series of different Caesar ciphers based on the letters of a keyword. It is a simple form of polyalphabetic substitution. The term Auto-Encipherment refers to ciphers in which the plaintext serves as its own key-phrase in the performance of Vigenre cipher. To the initial key append the plaintext.
