ZERO-HEADER STEGANOGRAPHY CREDENTIAL VAULT

Eliminate Plaintext Keys & Seeds with C127G Stego Vault

Infostealers and rogue AI plugins grep for .env, .pem, .kdbx, and seed.txt. C127G seals master API keys, SSH keys, and recovery seeds inside ordinary PNG/WAV carrier files using memory-hard Argon2id (256 MiB) + AES-256-GCM with zero identifying file headers.

  • Zero Vault Extension: Indistinguishable from standard RGB/PCM media
  • 256 MiB Argon2id KDF: Resists GPU brute-force clusters offline
