Description Ronald Wahl 2026-05-07 10:50:40 UTC

We use Crypt::OpenSSL::RSA for code signing which is currently version 0.37. On Fedora 44 we now get this error:

RSA.xs:983: OpenSSL error: illegal or unsupported padding mode

Looking at https://metacpan.org/dist/Crypt-OpenSSL-RSA/changes newer version may have fixed this. I already see build of version 0.41 for rawhide so maybe we can use it in F44 as well?

Reproducible: Always

Comment 1 Xavier Bachelot 2026-05-07 13:54:20 UTC

Could you please try packages from this scratch build ?

Comment 2 Ronald Wahl 2026-05-07 14:42:39 UTC

With that build the error message is gone.

Comment 3 Ronald Wahl 2026-05-07 14:54:41 UTC

But the generated signature is bad. Not sure yet if I need to change something when generating the signature.

Comment 4 Ronald Wahl 2026-05-07 15:06:23 UTC

I got it working. I now need to set the padding mode explicitly before signing otherwise some default is set that in my case was likely different then before.

Comment 5 Ronald Wahl 2026-05-07 15:27:02 UTC

For completeness I also checked setting the padding mode for the old version 0.37 of this package but unfortunately the PKCS#1 v1.5 padding mode was disabled for signing before version 0.38. So the update is required.
