Vigenère Cipher in Java • 01:48 - Input Message and Key • 02:38 - Mapping Key to Message • 06:02 - Creating Vigenere Table • 08:37 - Encryption • 10:26 - Decryption • 12:00 - key row to letter head of column • 14:26 - Testing the working of cipher • -*- Support on Patreon: / voxelpixel • -*- Source Code: https://github.com/VoxelPixel • Hi!! In this video I'll be coding vigenère cipher encryption and decryption using Java • Vigenère Cipher is a form of polyalphabetic subsitution, its algorithm is as following: • Take plaintext and a key • repeat key till its total length is equal to plaintext. • create a 26x26 table containing letters of alphabets, from second row, each row's letters r shifted to left by one position • -Encryption- • To encrypt, take a letter in plaintext along with its corresponding letter in key • use plaintext letter as column index and key's letter as row of vigenère table • row-column intersection's value is the ciphertext letter • -Decryption- • To decrypt, take a letter in ciphertext along with its corresponding letter in key • use key's letter as row index and letter heading of column which contains cipher letter is the required plain text
