Your assessors, primes, and auditors can check any CPCSC evidence receipt independently. No login required. No trust necessary. Just mathematics.
Enter an event ID to retrieve the cryptographic receipt from your evidence submission.
Your file never leaves this browser. SHA-256 hash is computed locally and compared against the cryptographic receipt. No data is transmitted to our servers.

Three pieces of information you need to understand
When you submit evidence to Solymus, we compute the SHA-256 hash of the file. This 32-byte hash is signed by AWS KMS using ECDSA P-256, the same algorithm used by governments and financial institutions worldwide. The signing key never leaves the HSM.
Third parties—auditors, assessors, or prime contractors—can verify any receipt without logging in. The public verification API exposes only the cryptographic proof: signature, algorithm, and Merkle chain linkage. No secrets. No audit logs. Pure mathematics.
When you export evidence, Solymus bundles the receipts into a JSON manifest with per-artifact verification URLs. Each URL points to this page with the event ID pre-filled. Assessors can verify offline or share verification URLs in their compliance reports.
We don't ask you to trust us. We ask you to trust mathematics.
The cryptographic primitives that secure CPCSC evidence are battle-tested in military, financial, and governmental systems.
