| Valid | 0 | The signature is intact, the signer's certificate chains to a trusted root and was valid when the document was signed, nothing was added to the document after the signature, and the certificate is not known to be revoked. |
| ValidWithWarnings | 1 | The signature is intact, but something needs attention: the certificate does not chain to a trusted root, content was added to the document after the signature, the certificate has expired since, or the time stamp could not be verified. Messages says which. |
| Indeterminate | 2 | The signature is intact, but whether it can be relied on cannot be decided: the signer's certificate was not valid when the document was signed, or its revocation status was asked for and could not be established. |
| Invalid | 3 | The signature does not match the bytes it covers - the signed content was changed or the signature is damaged - or the signer's certificate is revoked. |
