![]() ![]() ![]() I could figure out what happens and got it working now.Ĭonclusion: Word does not accept certificates that cannot be revoked because no CRL distribution point is specified in a certificate. Subject: CN = John Doe, emailAddress = Public Key Info:ĭigital Signature, Key Encipherment, Data Encipherment Signature Algorithm: sha256WithRSAEncryption I'd like to avoid having to trust individual certificates, which is why I have the CA. Why does Word not trust my Personal certificates and, more importantly, why to I have to trust individual certificates (people) when I already trust the certificates issuer (CA)? I think that this contradicts the principle of the chain of trust. What is causing the "recoverable signature" error? How to make a self-signed certificate 100% accepted without warnings?Īfter copying my (John Doe) certificate from Personal to Trusted People, the error disappears.Why is an internet connection actually required in this scenario? What does Word actually check (online)?. ![]() The result was the same as in the simplified scenario described above. I could verify that word requests the specified CRL (CRL without revocations). However, to make sure that Word does not expect one, I've tried a similar setup with an intermediate CA which specifies a CRL distribution point. My internet connection is working and the system clock is correct. This implies that both certificates are valid (not expired, not revoked). Both certificates are self-created / self-signed the root CA is installed as one of the trusted root certification authorities and I can see that the chain is trusted as expected. My certificate chain consists of a root CA and the certificate that I am using to sign the document. For me, the certificate (chain) is shown as valid. ![]() In most cases, a certificate in the chain is not trusted. Research showed that the issue seems to be quite common. The signer's certificate can't be verified, please try again later or check your network connection. I am able to sign the document anyway, but " Recoverable Signature" is shown in the signature field. The certificate you selected cannot be verified. I am trying to add a digital signature to a document in Microsoft Word for Microsoft 365 MSO (Version 2110). ![]()
