使用 MD5 哈希算法生成 ServicePartitionKey 很少返回 WindowsCryptographicException

Question

We are using MD5 Hashing Algorithm for generating PartitionKey to route to a stateful Service. For quite sometime we haven't seen any concerning issues in this approach. But, upgrading to .NET 6 we are seldomly seeing WindowsCryptographicException in the logs while trying to route to Stateful Service.

Area/Component: Stateful Services, PartitionKey generator

To Reproduce

private readonly MD5 _md5 = MD5.Create();

public long GetPartitionKey(string Id)
{
    var bytesToHash = Encoding.ASCII.GetBytes($"{Id}");

    var hash = _md5.ComputeHash(bytesToHash);
    var key = BitConverter.ToInt64(hash, 0);
    return key;
}

Expected behavior Shouldn't be returning any error. Observed behavior: {"Type":"WindowsCryptographicException","Message":"Unknown error (0xc1000008)","StackTrace":" at Internal.Cryptography.HashProviderCng.AppendHashData(ReadOnlySpan`1 source) at Internal.Cryptography.HashProvider.AppendHashData(Byte[] data, Int32 offset, Int32 count) at System.Security.Cryptography.HashAlgorithm.ComputeHash(Byte[] buffer) Screenshots If applicable, add screenshots to help explain your problem.

Service Fabric Runtime Version: 8.0

Environment:

Azure Linux If this is a regression, which version did it regress from? After upgrading to .NET6

Answer 1

We used .NET6 with stateful service and used the MD5 Hashing algorithm, able to run and deployed without any exceptions

Try to run the Visual studio as "Administrator" Below are the Service Fabric versions installed *

Used the GetPartitionKey code with MD5
