WebPost-Quantum Cryptography Challenge. What is Quantam Computer? Unlike classical computers that use binary digits (bits) to store and process information… 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. saks orthodontics mooresville
