Web7 apr. 2024 · There are two types of encryption – symmetric encryption and asymmetric encryption. ... (3DES) and Blowfish. Asymmetric encryption is when the sender and the receiver use different “keys” to encrypt and decrypt messages. Here a public key is used to encrypt the message, and a private key is used to decrypt the message. WebThere are several common encryption methods in use today. We cover ten popular algorithms in this post. 1. Triple-DES (3DES) Triple DES applies the older Data Encryption System (DES) algorithm three times to the same block of text. 3DES falls under the symmetric encryption that uses the block cipher method.
