Triple Data Encryption Standard (3DES)

Category: CompTIA Security+ Date: October 29, 2024

Triple DES, or 3DES, is an encryption algorithm that applies the Data Encryption Standard (DES) cipher three times to each data block for added security. It encrypts, decrypts, and then encrypts data again, making it more secure than standard DES but slower, and it’s commonly used in legacy systems.
