For every file added, we: 1. Derive a key from the passphrase ( PBKDF2‑HMAC‑SHA256 , 200 000 iterations). 2. Generate a fresh 16‑byte IV. 3. Encrypt the raw data with AES‑256‑GCM (provides confidentiality + integrity). 4. Store the encrypted blob as a regular file entry, and prepend a small 24‑byte “encryption header” ( b'NLZ' + version + salt + iv + tag ). | | **Automatic decryption** when reading an archive created with the feature. | Consumers don’t have to know the low‑level details; they just call extractall with the same passphrase. | During extraction the wrapper recognises the NLZ` header, pulls the salt/iv/tag, re‑derives the key, verifies the GCM tag and writes the plaintext to disk. |
If you have more details about where you encountered "ntrlegendzip" or what you're trying to accomplish, I could offer more tailored advice or information.
This is the most critical section. Searching for obscure .zip files on the internet comes with inherent risks.
