Local generation

RSA CSR and self-signed development certificates are generated in a browser worker. Private keys never enter the API request, server logs or storage. Save them deliberately and securely.

Inspection

Read public PEM/DER certificates and CSRs. CSR signatures are verified; certificate issuer trust is not inferred from the subject name. Fingerprints identify content, not trust.

Scope

This is a test/development profile, not a certificate authority. ECDSA, Ed25519, PFX, test CA chains and remote TLS acquisition require separate profiles and are not silently substituted.
