💡TripleDES is legacy and slower; prefer AES-GCM for modern encryption.
Legacy cipher. Prefer AES-GCM with random IV and authenticated encryption for modern apps.
About TripleDES
TripleDES (3DES) applies DES three times with different keys. It's considered legacy and slower than AES, with smaller block size and deprecation timelines in many standards.
Security Notes
Demo uses passphrase shortcut (CryptoJS). For real-world encryption use AES-GCM with KDF + random IV, and avoid DES/3DES for new systems.

FAQs
Is 3DES still safe?
3DES is considered legacy with deprecation in many standards; prefer AES-GCM for new systems.
Block size concerns?
3DES/DES use 64-bit blocks, making certain modes riskier at large volumes (birthday bound).
