GCM or CCM implementation of C#

Question

Can any one point me to any live implementation of CBC-MAC Mode (CCM)or Galois/Counter Mode (GCM) in C#? It seems that Microsoft has not created any implementation similar to AesCryptoServiceProvider. Am I right?

I did went through: https://blogs.msdn.microsoft.com/shawnfa/2009/03/17/authenticated-symmetric-encryption-in-net/, bit it's more of a "would look something like" rather than actual implementation. Any help will be highly appreciated. Thanks in advance.

That is not a correct duplicate. The OP just mis-named "Counter with CBC-MAC (CCM)" mode. — lockcmpxchg8b, Dec 12 '17 at 02:21
No, there's nothing inbox for it. It's on the TODO list, though https://github.com/dotnet/corefx/issues/7023. — bartonjs, Dec 12 '17 at 16:02

By the way, while there wasn't an official MS implementation at the time of this question, there is one now:

AES-GCM: AesGcm Class (System.Security.Cryptography)

AES-CCM: AesCcm Class (System.Security.Cryptography)

Both are supported from:

.Net: 5.0
.Net Core: 3.0
.Net Standard 2.1
