TripleDes encryption and decryption tool

1. Triple DES (3DES) is a symmetric-key encryption algorithm that extends the DES algorithm.

2. 3DES uses three different DES keys to perform three rounds of encryption or decryption on data, thereby enhancing the security of DES.

3. Due to the short key length of 3DES, it has largely been replaced by AES, and the use of AES is recommended.
