Issue Description

This is related to #18560, but since the work around is no longer working, I'm opening another issue.

When attempting to install the Apple Certificate with:

- task: InstallAppleCertificate@2
    displayName: 'Install Apple Distribution Certificate'
    name: iOSDistributionCertificate
    inputs:
      certSecureFile: '$(CertName)'
      certPwd: '$(iOSPrivateKeyPassword)'
      keychain: 'temp'
      opensslPkcsArgs: '-legacy'

I receive the following error:

/usr/local/bin/openssl pkcs12 -in /Users/runner/work/_temp/<certNameRedacted>.p12 -nokeys -passin pass:*** -legacy | /usr/local/bin/openssl x509 -sha1 -noout -fingerprint -subject -dates -nameopt utf8,sep_semi_plus_space

The previous workaround in adding the opensslPkcsArgs: '-legacy' seemed to fix the issue in the past, with older versions of openssl. However, it seems that the macos-13 image now has a newer version of openssl in where the -legacy parameter has been removed. You can see the "Unrecognized flag legacy" message in the above log.

So how can I get my iOS Apple Certificate installed? I'm open to suggestion.

Hi @SharpMobileCode, Thank you for the feedback! As I see openssl 3.1.4 and openssl 3.2 contains -legacy option which wasn't deprecated now.

Also, the error itself is different and not say that you have an old/unsupported certificate, are you sure that you're passing a valid certificate? Also could you please try to remove opensslPkcsArgs: '-legacy' and check will the error change?

[SharpMobileCode]

Hi @DmitriiBobreshev, thanks for response. I took at the certificate file again and it seem to have been corrupted in transit to me. When I would manually tried to install it I got an error. I had it regenerated and verified the new one wasn't corrupted. Uploaded to the Secure File Storage and now it seems to be working. So it seems it was just a bad file!

My apologizes, no bug intended. Thanks for the feedback!

Is there any resolution to this? I have the same problem also with macos-15. Had to change to macos-15 because XCode 16 was no longer supported on macos-14.

This affects me too :(
