KeelMatrix.Redaction

Privacy-first .NET text redaction primitives for masking secrets, tokens, PII, and noisy identifiers in logs, SQL, diagnostics, CI artifacts, and snapshot data.

Install

dotnet add package KeelMatrix.Redaction

What It Includes

  • built-in redactors for auth headers, API keys, JWTs, cookies, emails, GUIDs, IP addresses, phones, timestamps, URL tokens, and connection-string passwords
  • whitespace normalization for stable diffs and snapshots
  • a reusable RegexReplaceRedactor for custom masking rules
  • hardened regex creation with timeouts and, where safe, .NET 8 non-backtracking mode
  • zero external runtime dependencies

Quick Start

usingKeelMatrix.Redaction;ITextRedactor[]redactors={newAuthorizationRedactor(),newApiKeyRedactor(),newEmailRedactor(),newJwtTokenRedactor(),newWhitespaceNormalizerRedactor()};stringsanitized=rawText;foreach(ITextRedactorredactorinredactors){sanitized=redactor.Redact(sanitized);}

Common Use Cases

  • redact secrets before logging request, response, or SQL text
  • sanitize diagnostics before attaching them to CI artifacts or support tickets
  • remove rotating values so snapshot and approval tests stay stable
  • share a common redaction pipeline across libraries, services, tools, and test infrastructure

Design Notes

  • redactors are expected to be pure and idempotent
  • implementations are safe to compose in order
  • the library targets net8.0 and netstandard2.0
