An Enhanced Cipher Technique Using Vigenere and Modified Caesar Cipher

Cryptography is one amongst the foremost fields of study lately because it is critical to keep up the confidentiality of the info that is distributed over the network. There are a unit numerous cipher techniques out there for encrypting the messages like vern am cipher, mono-alphabetic cipher, poly-alphabetic cipher, etc. one amongst the foremost fashionable cipher techniques is that the vigenere cipher. It's a poly-alphabetic cipher technique that uses the vigenere table for the method of coding of alphabets. This paper extends the vigenere table with numerical knowledge, so the numbers may be encrypted exploitation this system. It combines the coding method of Vigenere and Modified Caesar Cipher for obtaining the cipher text from the given plaintext and key.
