Coding Signing Certificates: On behalf of RTR
Post by DDRM on Jan 3rd, 2016, 9:28pm
Dear All,
Richard asked me to copy this here, which he posted on the Yahoo site:
As many of you will know, Windows support for SHA-1 Code Signing Certificates ended yesterday. From now on, only SHA-2 certificates will be accepted as valid. This should not have any immediate effect on 'BBC BASIC for Windows' because although the version 6.00a installer and upgrade EXEs are signed with an SHA-1 certificate they are time-stamped with a date prior to today, and that should mean they are still accepted.
However, any EXEs that I generate from now onwards, which may include updates to BB4W or just compiled BASIC programs, will need to be signed with an SHA-2 certificate. I am currently in the process of obtaining one (I thought that replacing my existing SHA-1 certificate would be an 'instant' exercise but it seems not).
One particular thing to note is that SHA-2 certificates are only recognised by versions of Windows from XP SP3 onwards. If you are running Windows XP, please ensure that Service Pack 3 is installed; if you are still using an even older version (e.g. Windows 2000) then executables signed with an SHA-2 certificate will not be accepted.
Richard.
However, I note later in that strand that he has now discovered that his replacement certificate is still an SHA-1 one.
Best wishes
David
