SecretML v2.11

🆕 What's New in v2.11:

Version 2.11 introduces a new encryption method SHA256 Secure Mode-SML,
a patented encryption system that does not require memorizing a password phrase.

Key features:

• The encryption process uses both the hash of the file (file_hash) and your answers.

• Security is independent of the question length — without the core (file_hash), brute-force is impossible.

• file_hash is stored in the ZIP archive comment as a separate key in the format SHA256:.

• Think of the JSON file as the key and the archive comment as the lock's core — without the core, the lock cannot be opened.

• All data is securely locked: having the JSON and archive without the core is useless.

• You can split the key and the core between different people for extra security.

• Plausible deniability: just remove the archive comment, and the core is irreversibly lost.

• The key and archive can be stored together without risk, as long as the file_hash is missing.

• The final key for the archive is generated as:
  final_key = SHA256(SHA256(answer1 + file_hash) + SHA256(answer2+ file_hash) + SHA256(answer3+ file_hash) + ...).

SHA256 Secure Mode Security Assessment
The SHA256 Secure Mode method combines AES-256-CBC and SHA-256, providing multi-layer protection. The final key is derived from the file hash (file_hash) and the user's answers, making brute-forcing the key virtually impossible without both components.

Thanks to its unique structure (combining answer1 + file_hash and an additional "payload"), this method resembles split knowledge schemes but has no direct analogs among common solutions.

With properly chosen answers (strong passwords), the method offers a high level of cryptographic security and additional features, such as plausible deniability by removing the archive's comment.
