Encryption Algorithms Explained with Examples Megan Kaczanowski Cryptography, at its most basic, is the science of using codes and ciphers to protect messages. Encryption is encoding messages with the intent of only allowing the intended recipient to understand the meaning of the message. See more Diffie-Hellman is what's called a key exchange protocol. This is the primary use for Diffie-Hellman, though it could be used for encryption as well (it typically isn't, because it's more efficient to use D-H to exchange keys, then … See more RSA is named for the creators – Rivest, Shamir, Adleman – and it is a manner of generating public and private keys. Technically there are two RSA algorithms (one used for digital signatures, and one used for asymmetric … See more It depends on your use case. There are a few differences between the two algorithms - first, perfect forward secrecy (PFS), which we … See more WebIn cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with …
