Security Architecture

We built HellSecure with a paranoid security model. Our architecture assumes the server is hostile, placing ultimate trust only in your hands.

The Lifecycle of a File

1. Select File

2. Encrypt & Generate Key

3. Send Blob

4. Shred File

AES-256-GCM Encryption

The gold standard for encryption. Provides authenticated encryption, ensuring both confidentiality and data integrity.

Argon2id Key Derivation

We use Argon2id to derive strong encryption keys from secure entropy, protecting against brute-force attacks.

Zero-Knowledge Architecture

The decryption key is never sent to our servers. We cannot decrypt, read, or scan your files. A breach of our servers yields only useless encrypted blobs.

Zero Storage Guarantee

Once a file reaches its usage limit or expiration time, it is securely erased permanently. We do not keep backups.

Anti-Exfiltration

Our View-Only mode disables right-clicks, selection, and keyboard shortcuts, keeping data on the screen and off the disk.

Self-Destruct Mechanisms

Strict usage limits enforce exact control over how many times a file can be opened.
