dotnet-aes-extra

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

• AES-CTR
  Defined by NIST SP 800-38A.
• AES-CMAC
  Defined by NIST SP 800-38B and RFC 4493.
• SIV-AES
  Defined by RFC 5297.
  This is often referred to as AES-SIV.
• AES-CMAC-PRF-128
  Defined by RFC 4615.
  Registered by IANA as PRF_AES128_CMAC.
• PBKDF2-AES-CMAC-PRF-128
  Defined by RFC 8018 in combination with RFC 4615.

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

Usage

The released NuGet package and the .NET assemblies contained therein have the following properties:

• Strong Naming
• SourceLink
• IntelliSense
• Authenticode

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

• AesCtr is modeled after .NET's Aes.
  Use AesCtr.Create() instead of Aes.Create().

• AesCmac is modeled after .NET's HMACSHA256
  Use new AesCmac(key) instead of new HMACSHA256(key).

• AesSiv is modeled after .NET's AesGcm.
  Use new AesSiv(key) instead of new AesGcm(key).

• For AES-CMAC-PRF-128, AesCmacPrf128 is modeled after .NET's HKDF.
  Use AesCmacPrf128.DeriveKey() instead of HKDF.DeriveKey().

• For PBKDF2-AES-CMAC-PRF-128, AesCmacPrf128 is modeled after .NET's Rfc2898DeriveBytes.
  Use AesCmacPrf128.Pbkdf2() instead of Rfc2898DeriveBytes.Pbkdf2().
