Installation

Use the following command to install the NSec.Cryptography NuGet package:

$ dotnet add package NSec.Cryptography --version 24.4.0

Supported Platforms

NSec 24.4.0 is intended to run on all supported versions of .NET on the following platforms:

	`-x64`	`-x86`	`-arm64`	`-arm`
`win-`	✓	✓
`linux-`	✓		✓	✓
`linux-musl-`	✓		✓	✓

Please note:

For Windows, the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, 2019, and 2022 is required. This is part of the .NET SDK but might not be present on a clean Windows installation.
The AES-GCM implementation in NSec is hardware-accelerated and may not be available on all architectures. Support can be determined at runtime using the static IsSupported property of the NSec.Cryptography.Aes256Gcm class.
