Hi everyone,
I frequently use Okular to sign PDFs or to verify signatures. I came across a strange message on the signatures panel while reading a document I signed myself with a valid certificate issued by spanish authorities.
“Unknown certificate issue or corrupted data”
OTOH, it also states that “The signature is cryptographically valid.”
What does that tell me, exactly? If this would have been signed by someone else, this message would worry me.
BTW, when I analyze the validity with other tools (AutoFirma, browser tools) there is no such warning. All valid.
Cheers, Uwe
