Encryptions are vital for securing data because they scramble that data using an encryption algorithm, which often involves the use of a pre-shared key (PSK) to secure, unlock, and unscramble the information. Three types of encryptions include RSA, 3DES, and AES. RSA (Rivest-Shamir-Adleman) encryption uses cryptography algorithms with two keys and are great to use with VPNs and services with email and communication (Human, 2023). Its purpose is based more on the type of information that needs to be secured rather than the type of organization. 3DES (Triple Data Encryption Standard) encryption, which can use two keys or three keys, uses a process of encrypting, decrypting, and encrypting again; it is often used for financial companies (Human, 2023). Finally, AES (Advanced Encryption Standard) encryption uses a block cipher that is symmetric and should mainly be used for classified data, like data from large organizations or the government (Human, 2023).
