Don't take our word for it. Check it.
Paste or upload a CouthActs chain-of-custody certificate or provider credential. We check every hash and signature against our published keys and tell you whether anything was changed after CouthActs signed it.
The document is sent to CouthActs only to be checked; we don't store it. You can also verify offline with our public keys.
