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 This process is called encryptionor enciphering. The science that studies such secret communication is calledcryptology. How is cryptology used? Secret writing has WebAsymmetric-Key Cryptography . On the other hand, asymmetric key cryptography refers to an encryption technique wherein two different keys are used to encrypt and decrypt the data. This is comparatively harder to use as the data can only be unlocked by using 2 different keys.
