1. Generate a Triple DES Key

2. Encrypt Data

3. Decrypt Data

Security Considerations

• Key Management: Safeguard the Triple DES key (`key.pem`) using secure storage mechanisms.
• Secure Transport: When transmitting encrypted data, use secure channels such as HTTPS or SFTP to prevent interception.
• Key Length: Triple DES uses a 168-bit key, which is considered relatively secure but not as strong as modern encryption algorithms like AES.
• Padding: Ensure proper padding mechanisms to avoid potential cryptographic attacks, such as padding oracle attacks.

Using OpenSSL with Triple DES involves generating a key, encrypting and decrypting data. Here's a brief summary of the process:

1. Key Generation: Use openssl genpkey to generate a Triple DES key.
2. Encryption: Encrypt data with openssl enc using the Triple DES algorithm.
3. Decryption: Decrypt encrypted data with openssl enc.
4. Security Considerations: Manage keys securely, use secure transport channels, and ensure proper padding mechanisms.

Triple DES is a legacy encryption algorithm, and while it's still in use in some systems, it's generally recommended to migrate to more modern encryption standards like AES for improved security and performance.
