dotnet-aes-extra

.NET Standard 2.0 implementation of the following AES modes that are not included in .NET 6.0 / .NET Framework:

• AES-CTR, as defined by NIST SP 800-38A
• AES-CMAC, as defined by NIST SP 800-38B
• SIV-AES, as defined by RFC 5297
  (Note: this is often refered to as AES-SIV, but the original RFC specification uses the name SIV-AES)

The implementation is for AnyCPU, and works on all platforms.

Usage

The released binary NuGet packages and the .NET assemblies contained therein:

• use Strong Naming,
• include SourceLink,
• include IntelliSense compatible documentation, and
• are signed and timestamped with Authenticode.

All public classes are in the Dorssel.Security.Cryptography namespace.

• AesCtr is modeled after .NET's Aes. So, instead of Aes.Create(), use AesCtr.Create().
• AesCmac is modeled after .NET's HMACSHA256. So, instead of new HMACSHA256(key), use new AesCmac(key).
• AesSiv is modeled after .NET's AesGcm. So, instead of new AesGcm(key), use new AesSiv(key).
