This suggests to me that there could be an iOS specific bug in the Slice logic we just added in #87514:

runtime/src/libraries/System.Security.Cryptography/src/System/Security/Cryptography/X509Certificates/X509Certificate.cs

Lines 716 to 718 in 369301f

	KdfWorkLimiter.SetIterationLimit((ulong)pkcs12UnspecifiedPasswordIterationLimit);
	ulong observedIterationCount = GetIterationCount(pkcs12, out int bytesConsumed);
	pkcs12 = pkcs12.Slice(0, bytesConsumed);

[akoeplinger]

@jozkee that change got backported to 7.0 right?

[jozkee]

@akoeplinger yes, and to 6.0 and 3.1 as well.

EDIT: actually no, the Slice change is currently only on 8.0.

[jozkee]

Do you think this could be a regression?

[akoeplinger]

Could be, I'll try to repro it locally and see if reverting the change fixes it.

[akoeplinger]

@jozkee I confirmed that the test failures don't happen with #87514 reverted. ... which makes sense since it's one of the tests added in that PR that fails 😄
