OnixLabs.Security 15.0.0

ONIXLabs .NET Library

The ONIXLabs .NET Library is a suite of general-purpose, production-ready libraries designed to support modern application development with a strong emphasis on correctness, composability, and value semantics. They are designed to integrate cleanly into both small utilities and large-scale systems, without imposing architectural constraints or framework lock-in.

At a high level, ONIXLabs provides:

• Foundational primitives and patterns missing or underrepresented in the BCL
• Functional and value-oriented abstractions for safer code
• High-precision numeric and generic math utilities
• Security and cryptography APIs with strong typing and value semantics
• Infrastructure helpers that reduce boilerplate while preserving clarity

Current .NET Support includes .NET 8.0, 9.0 and 10.0, and all packages are published to Nuget.

Package Overview

• OnixLabs.Core – Foundational primitives, patterns, and extensions
• OnixLabs.DependencyInjection – Configuration-driven DI registration
• OnixLabs.Numerics – Arbitrary-precision numbers and generic math
• OnixLabs.Security – Non-cryptographic security utilities
• OnixLabs.Security.Cryptography – Cryptographic primitives and structures

OnixLabs.Core

See it on Nuget

Foundational primitives, patterns, and extensions that address common gaps in the .NET Base Class Library. This package provides low-level building blocks used throughout the ONIXLabs ecosystem, but is also useful as a standalone utility library in any .NET application.

• Strongly typed enumeration pattern (Enumeration<T>)
• Functional patterns (Optional<T>, Result, Result<T>)
• Preconditions and guard clause utilities
• Specification pattern with LINQ-compatible expressions (Specification<T>)
• Value semantics interfaces (IValueEquatable<T>, IValueComparable<T>)
• Binary conversion abstractions (IBinaryConvertible, span- and memory-based variants)
• Collection generators with LINQ-style query support
• Extension methods for arrays, objects, strings, comparables, random, and more
• Extensions for IEnumerable, IEnumerable<T>, and IQueryable<T>
• Reflection helpers for Type
• Strongly typed Base16, Base32, Base58, and Base64 text types
• Extensions for StringBuilder and Encoding

OnixLabs.DependencyInjection

See it on Nuget

Lightweight extensions for Microsoft’s dependency injection abstractions, focused on reducing boilerplate and improving configurability of service registration.

• IServiceCollection extensions
• Configuration-driven service lifetime selection
• Cleaner, more consistent registration APIs

OnixLabs.Numerics

See it on Nuget

High-precision numeric types and generic math utilities for scenarios where built-in numeric types are insufficient. This package emphasizes correctness, precision, and introspection of numeric values.

• Arbitrary-precision BigDecimal based on generic math (IFloatingPoint<T>)
• Extended-width integer types (Int256, UInt256, Int512, UInt512)
• Extended-precision floating-point types (Float128, Float256)
• NumberInfo for dissecting rational numbers into constituent parts
• Generic numeric abstractions (IBaseNumber<T>, INumber<T>)
• Extension methods for Decimal, BigDecimal, BigInteger, and other numeric types

OnixLabs.Security

See it on Nuget

Non-cryptographic security utilities focused on safe generation and handling of security-related values.

• SecurityToken generation
• Support for pseudo-random and cryptographically secure RNGs
• Configurable token alphabets (upper, lower, numeric, special characters)

OnixLabs.Security.Cryptography

See it on Nuget

Strongly typed cryptographic primitives and structures with value semantics, designed to make cryptographic operations safer and more explicit.

• Public and private key abstractions (PublicKey, PrivateKey)
• ECDH, ECDSA, and RSA key implementations
• Digital signature types (DigitalSignature, DigitalSignatureAndPublicKey)
• Cryptographic hash value types (Hash, NamedHash)
• Extensions for HashAlgorithm
• Fully managed FIPS-202 SHA-3 implementation (SHA3-224/256/384/512, SHAKE128/256)
• Merkle tree implementations (MerkleTree, MerkleTree<T>)
• Cryptographic salt value type (Salt)
• Encrypted-in-memory secret handling (Secret)
• Common cryptographic primitive abstraction (ICryptoPrimitive)
