WebFeb 17, 2024 · Cryptography is based on the use of a pair of keys, one public and one private, to encrypt and decrypt data. The public key can be freely distributed to anyone, while the private key is kept secret by the owner. When a message is encrypted with the public key, only the owner of the corresponding private key can decrypt it.

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.
