WebAug 28, 2024 · Public-key cryptography or asymmetric cryptography involves two keys: a public key and a private key. The public key is available publicly and used for encryption, while the private key is kept secret between two parties and used for decryption. Encryption strength is usually measured by key size. WebCodes and ciphers are forms of secret communication. A code replaces words, phrases, or sentences with groups of letters or numbers, while a cipher rearranges letters or uses substitutes to disguise the message. This process is called encryption or enciphering. The science that studies such secret communication is called cryptology.
