Pull Request Overview
Updates the PKCS#12 test fixture to use a SHA-1 MAC for Windows compatibility, replacing the previous SHA-256 MAC–encoded blob.
- Replaces the base64 PFX data for
IetfSlhDsaSha2_128sCertificatePfx_Pbes1with a new blob using SHA-1 MAC. - Ensures Windows 10 Threshold can import the test PFX.
Comments suppressed due to low confidence (1)
src/libraries/Common/tests/System/Security/Cryptography/AlgorithmImplementations/SlhDsa/SlhDsaTestData.cs:385
- There’s no test that validates the MAC algorithm on the new PFX blob. Consider adding a test that loads this PFX and asserts its MAC OID is the SHA-1 OID (1.3.14.3.2.26) to prevent regressions.

The PKCS#12 document in
IetfSlhDsaSha2_128sCertificatePfx_Pbes1usedpbeWithSHA1And3-KeyTripleDES-CBCfor key and certificate encryption, but it still used SHA-256 for the MAC, which Windows 10 Threshold does not support. This pull request re-encodes it to use a SHA-1 MAC.Contributes to #115270 (not marking as fixing until Build Analysis shows a 0 24-hour hit count)
