Dear all,I have obtained numerical certificates of national certification authority in Czech Republic (ICA).
1/ I have imported the certificate into Mozilla Thunderbird > Account Settings > Security > Digital Signing.
- It shows Software Security Device:TwinsQS 10/07/2015. - Digitally sign messages (by default) is ticked.In Certificates > View Certificates, I obtain "Your certificates". I click on my certificate, and read:
"General > This certificate has been verified for the following uses: SSL client certificate, SSL server certificate, Email Signer certificate, Object Signer. "However, Mozilla Thunderbird > Account Settings > Security > Encryption is greyed.
Clicking on "Select..." leads to error message"Certificate Manager can't locate a valid certificate that other people can use to send you encrypted email messages."
2/ If I send a new email to a coworker also working with Thunderbird on Linux, (or another on Outlook on Windows), he obtains :
Email is signed. Signature is valid.However, my computational center want to send me a password by using my certificate to encrypt their email. Problem is that they don't have the file for this. Which file should I send them ? Which file format should I send ? I have too many formats existing. DER, CER, PFX, P7C, PK7, CRT... - Why Thunderbird cannot import my certificate to encrypt emails ? That would solve my issue. - Why is there no option to attach my key into Thunderbird ? It is present in OpenPGP but I would like to use S/MIME without this OpenPGP.
Thanks a lot for your help! Best regards, Thibault
