![]() ![]() ![]() Some commonly used encryption algorithms include Blowfish, Advanced Encryption Standard (AES), Rivest Cipher 4 (RC4), RC5, RC6, Data Encryption Standard (DES), and Twofish.Įncryption has evolved over time, from a protocol that was used only by governments for top-secret operations to an everyday must-have for organizations to ensure the security and privacy of their data. Even though the encrypted data appears to be random, it can actually be turned back into plaintext by using the key again. An algorithm will use the key to alter the data in a predictable way. Cybercriminals increasingly have access to stronger computing power such that sometimes, when vulnerabilities exist, they are able to gain access.ĭata needs to be encrypted when it is in two different states: "at rest," when it is stored, such as in a database or "in transit," while it is being accessed or transmitted between parties.Īn encryption algorithm is a mathematical formula used to transform plaintext (data) into ciphertext. ![]() These two keys are known as a public key and a private key. Asymmetric encryption, also known as Public-Key Cryptography, encrypts and decrypts the data using two separate cryptographic asymmetric keys. Original information, or plain text, might be something as simple as "Hello, world!" As cipher text, this might appear as something confusing like 7*#0+gvU2x-something seemingly random or unrelated to the original plaintext.Įncryption, however, is a logical process, whereby the party receiving the encrypted data-but also in possession of the key-can simply decrypt the data and turn it back into plaintext.įor decades, attackers have tried by brute force-essentially, by trying over and over again-to figure out such keys. The two main types of data encryption are asymmetric encryption and symmetric encryption. ![]()
