🔏 Meerkat e-Seal Signer

Paste a SHA-256, SHA-384, or SHA-512 hash digest to receive a CAdES-T CMS signature from the Meerkat e-Seal authority. Includes an embedded RFC 3161 signature timestamp. Download the .cms token and inspect it inline.

🔒 The hash you provide is sealed using ECDSA P-256 — your original content never leaves your machine. A CAdES-T signature timestamp is embedded via the Meerkat TSA. Issued tokens are signed by the Meerkat e-Seal authority (not a qualified TSP — for testing only).
