WebAssuming that your encryption method was secure, then your counter stream should be pseudo-random to anyone who doesn't know how you encrypted it. So, you can XOR messages with the encrypted counter stream. Note that this is like how a … WebIn cryptography, a message authentication code ( MAC ), sometimes known as an authentication tag, is a short piece of information used for authenticating a message. In other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed.

cryptography - What makes a symmetric encryption algorithm

WebCryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used.
