Bit shifting encryption
WebJan 1, 2015 · The integral part of this algorithm is its key encryption and decryption method. A special attention has given to secure the secret key better to say to secure the shared link using a circular bit shifting operation and folding method. It is hard to decipher the key and to decrypt the ciphered text without knowing the proper key. WebDec 1, 2016 · 1 Answer.
