Member nameValueDescription
Valid0 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.
ValidWithWarnings1 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.
Indeterminate2 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.
Invalid3 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.
