Buypass Signature Validation

About Buypass Signature Validation

Buypass Signature Validation is a service under the Buypass Cloud Signature Service portfolio. This service operates independent of other Buypass services and may be used by any party that have been granted access by signing service agreement with Buypass or via a Buypass reseller/partner.

Given a minimal request, the validation service will try to construct the complete certificate chain and fetch all available revocation data needed to validate the signing certificate and verify the signature. The service support both validation within the validity period of the signing certificate, and long term validation. If no ocsp or crl is provided, the remote signing api will validate that the certificates are vaild now. If the certificate has been revoked between the signing time and validation time, the validation api will declare the signature for invalid, since it is impossible to determine whether the certificate was valid at the time the signature was created.
