Document

QryptChat

Quantum-resistant, end-to-end encrypted messaging.

What you can do

  • Send encrypted messages to other QryptChat users
  • Make ML-KEM-1024 encrypted voice and video calls
  • Share files with end-to-end encryption
  • Set disappearing messages
  • Register with just a phone number — no email required

Authentication

Phone number + SMS verification code. No passwords.

API

No public API. Self-hostable via the open-source repo at https://github.com/profullstack/qryptchat-web

Trustgrade A

  • passBody integrity

    Whether the stored document is plausibly the kind of file the artifact declares, rather than something fetched by mistake.

  • passType matchnot applicable to this artifact type

    Whether the artifact is really the kind of thing its metadata claims it is.

  • passFreshness

    How long since the source repository was last pushed to.

  • passPrompt injection

    Scans the artifact's own text for instructions aimed at your agent rather than at you.

  • passLicense

    Whether the source repository declares an SPDX license permissive enough to redistribute.

How the grade is calculated

Each check contributes 0 points when it passes, 1 when it warns, and 2 when it fails. The total maps to a letter:

  • Aevery check passed
  • Bone warning
  • Ctwo warnings
  • Dprompt injection or body integrity failed, or three warnings
  • Fone of those failed, and something else is wrong

These are automated hygiene checks, not a security audit, and not a dependency or vulnerability scan. A grade of A means nothing was flagged — not that the artifact is safe.
