What Is an Encryption Algorithm?
Encryption is the science of making a text unreadable in order to pass it securely and secretly to the intended recipient, who uses a key to decrypt the message. An encryption algorithm is a defined series of steps for encrypting data. The original text is referred to as plaintext, and after the encryption algorithm has been applied to it, it is called ciphertext. The encryption algorithm may be referred to as a cipher, and is often given a name. For example, there is one encryption algorithm named Blowfish and another named AES (Advanced Encryption Standard), for example.
