What is Triple DES?

Triple DES is an encryption algorithm based on the original Data Encryption Standard (DES). It is a symmetric encryption algorithm that uses multiple rounds of the Data Encryption Standard (DES) to improve security. It is also known as Triple DES because it uses the Data Encryption Standard (DES) cypher which takes three times to encrypt its data. It is essentially a block cypher used to encrypt data in 64-bit blocks. Security-wise, it outperforms the original Data Encryption Standard (DES). However, Triple DES is less efficient and slower than the Advanced Encryption Standard (AES).
