Core Architecture

Impenetrable Personal Vault

Protect your bank accounts, crypto recovery phrases, and personal logins. C127G is 100% air-gapped from the internet, meaning your most sensitive credentials can never be leaked in a cloud server breach.

Developer .env Export

Stop copy-pasting API keys and database strings. Select multiple secrets from your vault and instantly generate a formatted `.env` file directly into your local coding project.

True Pixel Steganography

Hide in plain sight. C127G uses Least Significant Bit (LSB) manipulation to mathematically weave your heavily encrypted vault payload directly into the pixels of a standard `.png` image. To forensic scanners, it just looks like a normal photo.

Plausible Deniability

Create a secondary "decoy" master password. If you are ever forced to unlock your computer under duress, enter the decoy password to display a dummy vault filled with fake data.

Air-Gapped Sharing

Generate self-destructing, password-protected `.c127g` files to securely pass credentials to coworkers over Slack without plain-text exposure.

Quantum-Resistant Cryptography

Built to protect against "Store Now, Decrypt Later" attacks. C127G relies on industry-standard, peer-reviewed cryptographic primitives. No telemetry. No network requests.

  • Argon2id Key Derivation

    Your master password is hashed using a massive 256 MiB memory cost algorithm, aggressively thwarting brute-force and GPU dictionary hacking attempts.

  • AES-256-GCM Encryption

    Your private data is secured using raw AES-256-GCM, providing a future-proof 128-bit quantum security margin with mathematical integrity.

  • Compiled Machine Code

    C127G is distributed as raw, compiled machine code, drastically complicating reverse-engineering attempts by malicious actors.
