DSInternals Common Library

Introduction

The DSInternals.Common package is the foundational library shared between other DSInternals packages. It provides core cryptographic functionality and abstractions for working with Active Directory security data.

As this library uses Windows-specific cryptographic APIs (P/Invoke), it is only supported on Windows.

Key Features

• Password Hash Computation: Calculate NT hash, LM hash, and OrgId hash values
• Kerberos Key Derivation: Generate Kerberos keys from passwords
• Key Credential Parsing: Parse and create NGC, FIDO2, and STK key credentials
• Active Directory Credential Extraction: Decrypt password hashes, LAPS passwords, DPAPI certificates, and DNSSEC keys stored in Active Directory

Usage Examples

Computing NT Hash

using DSInternals.Common.Cryptography;

// Compute NT hash from a plain-text password
byte[] ntHash = NTHash.ComputeHash("MyPassword123");
