This a new algorithm in which we encrypt on the basis of position of the character. Algorithm 1 for key generation and Algorithm 2 is for encryption Algorithm A1 Step1: Let the key be ‘k’. Step2: Multiply the index number +1 with its ASCII c

BLAKE2 are cryptographic hash functions based on Dan Bernstein s Cha stream cipher, but a permuted copy of the input block, XORed with some round constants, is added before each Cha round. Like SHA-2, there are two variants differing in the word size
