The current Windows code signing certificate is about expire (on March 26th 2020). As I have volunteered to take over the Windows code signing duties, I’ve purchased a new Windows code signing certificate with the same CA and under the same organization (Bitcoin Core Code Signing Association).
A signature by the old certificate over the new certificate has been provided to me. This signature can be verified using
0openssl cms -verify -inform pem -purpose any -content path/to/new/win-codesign.cert -CAfile path/to/old/win-codesign.cert -certfile path/to/old/win-codesign.cert
The verification should succeed and the new certificate will be printed out. This can be compared to the contents of win-codesign.cert
.
