renew code signing cert for Windows

Estimated time:


Due to StartCom's validility being questioned (at least in Browser), look for alternatives. (current cert is valid until end of May 2018)

Note: We only needed an Extended Validility cert from StartCom, because their regular code-signing cert didn't support the corresponding flag in the cert.
As we don't do hardware drivers or kernel modules, we're fine with an Authenticode/Multi Purpose certificate.

The typical vendors come to mind:
Thawte, Symantec/Verisign, DigiCert

Price is around 200-250USD/year, depending on validation period (up to three years)
has a small (and slightly outdated) comparison, also includes GoDaddy

Other vendors are GlobalSign and Comodo.

Symantec messed up just recently, issuing a bunch of testcertificates second strike for them, so leaning towards digiCert at the moment.

#3 Updated by Florian Effenberger 10 months ago

Is digicert the way to go now, shall I proceed with them, or do you do further research?

#5 Updated by Christian Lohmaier 10 months ago

go with digicert I'd say. I'll create corresponding certificate signing request after reading their fine print

#6 Updated by Christian Lohmaier 8 months ago

signing request with:
CN =
C = DE
O = The Document Foundation
S = Berlin
L = Berlin
STREET = Kurf├╝rstendamm 188
E =
OU = LibreOffice Build Team

(and of course with "Enhanced Key Usage: Code Signing" and no Lifetime Signing (i.e. valid after cert expires). Also added Time Stamping and Microsoft Time Stamping like with the StartCom one in the past, sha256RSA, 4096bit keysize)

reassing to floeff for the digicert paperwork)
