// About Random Password Tool

Developer-focused CSPRNG generation and API security guidance. Written by practitioners, for practitioners.

// Mission

// tl;dr — Correct CSPRNG implementation, verifiable in DevTools, with the code examples and API design patterns engineers actually need.

Random Password Tool exists to give developers a correct, auditable reference implementation of cryptographically secure password generation — paired with the practical code patterns for integrating that generation into APIs, CI/CD pipelines, and IAM provisioning workflows.

Most password generator tools are marketing pages that ship Math.random() behind a polished UI. This tool ships crypto.getRandomValues() with the Network tab open as the proof. Every claim on this site comes with a primary source: NIST SP 800-90A, OWASP Cryptographic Storage Cheat Sheet, CISA Secure by Design, or RFC.

// About the Author

Ateeq Y Tanoli is a security engineer with deep experience in cryptographically secure random number generation, API security architecture, DevSecOps pipeline design, and credential lifecycle management across enterprise environments.

Alex has contributed to internal OWASP working group discussions on the Cryptographic Storage Cheat Sheet and has implemented NIST SP 800-63B compliant credential management systems across financial services and healthcare environments subject to PCI-DSS v4.0, HIPAA, and ISO 27001 audit requirements.

// Technical focus areas

  • CSPRNG implementation — crypto.getRandomValues(), Node.js crypto.randomBytes(), OS entropy sources (/dev/urandom, CryptGenRandom)
  • API security design — rate limiting strategies, CORS, response headers, charset validation, cache control
  • Secrets management — HashiCorp Vault, AWS Secrets Manager, SOPS, GitHub Actions secret injection
  • IAM provisioning — SCIM 2.0, Active Directory bulk provisioning, Entra ID, mandatory rotation workflows
  • DevSecOps — pipeline secret scanning (Trufflehog, GitLeaks), environment promotion patterns, dev/staging/prod credential isolation
  • Compliance — PCI-DSS v4.0 Req 6.2, NIST SP 800-90A/800-63B, OWASP Top 10, CISA Secure by Design

// Why Trust This Tool?

🔒Verifiable client-side

All generation uses crypto.getRandomValues(). Open DevTools → Network — zero requests made during generation.

📋Primary sources only

Every claim cites NIST, OWASP, CISA, or RFC. No paraphrased marketing guidance.

⚡No Math.random()

The tool itself never calls Math.random() for generation. Educational content explains why you shouldn't either.

🚫No advertising

Affiliate links are disclosed individually per ASA/FTC rules and do not influence technical recommendations.

// Editorial Standards

All technical claims are sourced from: NIST SP 800-90A, NIST SP 800-63B 2025, OWASP Cryptographic Storage Cheat Sheet, CISA Secure by Design, and relevant RFCs. No claim is published without a primary source published within the last three years.

Code examples are tested against Node.js LTS, Python 3.12+, and current browser environments before publication. Security-critical code examples are reviewed against OWASP guidance before being included in the Code Generator.
