Encrypting and decrypting data
In .NET, there are multiple encryption algorithms you can choose from.
In legacy .NET Framework, some algorithms are implemented by the OS and their names are suffixed with CryptoServiceProvider or Cng. Some algorithms are implemented in the .NET BCL and their names are suffixed with Managed.
In modern .NET, all algorithms are implemented by the operating system. If the OS algorithms are certified by the Federal Information Processing Standards (FIPS), then .NET uses FIPS-certified algorithms rather than implementing the algorithm in the .NET base class library.
Cryptographic operations are performed by operating system implementations so that when an OS has a security vulnerability fixed, then .NET apps benefit immediately. But this means that those .NET apps can only use features that an OS supports. You can read about which features are supported by which OS at the following link: https://docs.microsoft.com/en-us/dotnet/standard...
