%X The Vigen¨¨re Cipher is a traditional method which involves encrypting alphabetic text by using a series of different Caesar Ciphers based on the letters of a keyword. The Vigen¨¨re Cipher works on the set of 26 English alphabets. In this paper we introduce the Alpha-Qwerty Cipher and reverse Alpha-Qwerty Ciphers which are the extensions to the Vigen¨¨re Cipher. This cipher works on a set of 92 characters by introducing case sensitivity and by adding digits and some other symbols to the existing Vigen¨¨re Cipher which is of 26 characters. This paper also modifies the mapping sequence from the plain text to the cipher text.
