Azure DevOps InstallAppleCertificate Fails with OpenSSL Flag -legacy on macOS Agent

[jaimisdomadiya]

The InstallAppleCertificate task in Azure DevOps is failing on macOS agents when attempting to parse a valid .p12 certificate. The failure occurs during the OpenSSL command execution with the following error:

pkcs12: Unrecognized flag nodes -legacy pkcs12: Use -help for summary. unable to load certificate 140704446801536:error:0909006C:PEM routines:get_name:no start line:crypto/pem/pem_lib.c:745:Expecting: TRUSTED CERTIFICATE

Steps to Reproduce
Set up an Azure DevOps pipeline using the InstallAppleCertificate task.
Use a valid .p12 certificate file (tested locally and verified to be working).
Add the opensslPkcsArgs: '-legacy' argument to the task to ensure compatibility with legacy certificates.
Run the pipeline on a macOS agent (macOS-15 or macOS-14).

Expected Behavior
The .p12 certificate should be parsed successfully, and the certificate should install without errors.

Actual Behavior
The task fails with the error:
pkcs12: Unrecognized flag nodes -legacy unable to load certificate 140704446801536:error:0909006C:PEM routines:get_name:no start line:crypto/pem/pem_lib.c:745:Expecting: TRUSTED CERTIFICATE

Environment Details
Azure DevOps Pipeline Agent: macOS-15
OpenSSL Version: [Include version after debugging step]
Task Version: InstallAppleCertificate v2.246.5
Certificate: .p12 file verified to be valid locally.
