Top 20 NuGet cryptography Packages

Chaos.NaCl cryptography library
SIMON and SPECK are families of lightweight block ciphers; those block ciphers are efficient and provide high performances across a wide range of devices. This package includes classes that allow you to encrypt and decrypt using native libraries that are using SIMD such as AVX2 or NEON.
BouncyCastle.Crypto is a cryptography API providing: -Generation and parsing of PKCS#12 files. -X.509: Generators and parsers for V1 and V3 certificates, V2 CRLs and attribute certificates. -PBE algorithms supported by PBEUtil: PBEwithMD2andDES-CBC, PBEwithMD2andRC2-CBC, PBEwithMD5andDES-CBC, PBE...
A package to digitally sign and verify data(i.e. documents,etc)
A .NET wrapper to invoke a C implementation of Argon2.
A library containing classes to deal with some crypto functions at a convenient level. [Note: This library is not quite ready for public consumption--I'm in the middle of some code reorganization]
Security helpers and extensions for System.Security.Claims.
Fluent assertions related to Moon.Security.
Symmetric, hashed and base64 utility methods and extensions
Zephyr is the namespace for utility libraries in Synapse; Zephyr utilities are suitable for stand-alone usage outside Synapse. Synapse is a lightweight execution engine for unifying federated data sources and processes. The Crypto utilitiy library supports RSA and Rijndael encrryption and Base64 enc...
