Bug ID: 453342
Summary: KMail bad signature when using S/MIME
Product: kmail2
Version: 5.19.2
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: crypto
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
When sending a signed email in the S/MIME format, the email is marked to have
"invalid signature" when read.
If instead S/MIME opaque is selected, the signature is recognized valid by the
sender account, invisible by others.
STEPS TO REPRODUCE
1. Select S/MIME signing mode from settings
2. Set an X.509 certificate for signing
3. Send signed email
OBSERVED RESULT
When sending a signed email in the S/MIME format, the email is marked to have
"invalid signature" when read.
If instead S/MIME opaque is selected, the signature is recognized valid by the
sender account, invisible by others.
EXPECTED RESULT
Of course signature should always be visible no matter the recipient, and valid
no matter the signing format.
