Without modern cryptography techniques, the Internet as we know it would not exist. Secure communications enable virtually all online interaction. Encryption algorithms permit the secure exchange of data and confident verification of identity. Without these common cryptographic tools, our modern connected society could not function as it does today. Symmetric Key Encryption Algorithms Symmetric key encryption algorithms rely on a secure password to act as the key. This is the oldest form of encryption. Symmetric keys form the basis of everything from combination locks to modern hard drive encryption. AES, DES, and Blowfish are all modern symmetric key encryption algorithms.
