A modern cryptographic library for .NET based on libsodium, offering easy-to-use and secure-by-default APIs.
NSec is a cryptographic library for .NET that provides modern cryptographic primitives by building on libsodium. It offers a contemporary API using Span<T> to make cryptography easier to use, secure by default, and performant for .NET applications.
.NET developers who need to implement cryptography in their applications, particularly those looking for a modern, secure, and easy-to-use alternative to lower-level or older cryptographic APIs.
Developers choose NSec for its modern API design, security-by-default approach, and strong performance, all backed by the trusted libsodium library, which simplifies cryptographic implementation while reducing common pitfalls.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Utilizes Span<T> for efficient memory handling and a clean, type-safe interface, making it contemporary and performant, as highlighted in the README's focus on modern .NET features.
Designed to prevent common cryptographic mistakes with safe defaults and clear abstractions, aligning with the project's philosophy of reducing complexity and risk.
Optimized for speed through efficient algorithms and minimal overhead, leveraging libsodium's robust implementations for fast cryptographic operations.
Supports easy updates and algorithm agility to adapt to evolving security standards, ensuring future-proof cryptography as mentioned in the key features.
Built on the widely-trusted and audited libsodium library, providing robust cryptographic implementations with a proven track record for security.
The NuGet package is currently in preview (26.1.0-preview.1), indicating it might not be fully stable for production and could have breaking changes, as shown in the README badge.
Requires libsodium, which can complicate deployment and setup, especially on platforms where native binaries need manual installation or management.
Inherits limitations from libsodium, such as lack of support for certain legacy or niche cryptographic algorithms, which might not cover all use cases.
Despite being designed for ease of use, it still requires a good understanding of cryptographic concepts to implement correctly, which could be a barrier for developers new to the field.
