About TripleDES Encryption
Triple DES (3DES or TDES) is a symmetric-key block cipher that applies the Data Encryption Standard (DES) algorithm three times to each data block. It was designed to provide a more secure alternative to standard DES, which was becoming vulnerable to brute-force attacks.
Security Notes:
- Always use a strong, unique key for encryption
- For CBC, CFB, and OFB modes, use a unique initialization vector (IV) for each encryption operation
- Store your encryption keys securely
