Security tools that respect your privacy
All password and hash tools in this hub run entirely in your browser — no input data is ever transmitted to a server. That means you can safely use these tools with real passwords, keys, or sensitive strings during development and testing.
For developers and security engineers: The hashing tools cover the most commonly encountered algorithms — MD5, SHA-1, SHA-256, SHA-512, HMAC, and bcrypt — making this a fast reference and generation hub for everyday security work.
7 Password & Hash Tools
Each tool is purpose-built for a specific task. No bloat, no gated features.
Password Generator
Generate strong, cryptographically secure random passwords with full control over length, character sets (uppercase, lowercase, numbers, symbols), and exclusion rules. All generation happens in-browser.
Password Strength Checker
Analyse the strength of any password against entropy, length, character variety, and known pattern vulnerabilities. Get a score and specific improvement suggestions — processed entirely client-side.
Hash Generator
Generate cryptographic hashes for any input string using MD5, SHA-1, SHA-256, SHA-384, and SHA-512 simultaneously. Useful for verifying hash consistency across algorithm choices.
MD5 Generator
Generate MD5 hashes for any text string. Despite its known cryptographic weaknesses, MD5 remains widely used for checksums, file integrity verification, and non-security-critical fingerprinting.
SHA Hash Generator
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes for any input. SHA-256 and SHA-512 are recommended for security-critical applications and digital signature workflows.
HMAC Generator
Generate HMAC (Hash-based Message Authentication Code) signatures using MD5, SHA-1, SHA-256, or SHA-512 with a secret key. Essential for API request signing and webhook verification.
Bcrypt Hash Explainer
Decode and explain bcrypt hash strings — breaking down the algorithm version, cost factor (work rounds), salt, and hash components. Includes a generator for producing bcrypt hashes at configurable cost factors.
Common scenarios these tools solve
Purpose-built for professionals and everyday users who need fast, reliable results.
Developers
Generate hashes for test data, verify bcrypt rounds are configured correctly, and create HMAC signatures for API authentication testing.
Security Engineers
Check password strength against NIST guidelines, generate cryptographically secure random passwords for credentials rotation.
Penetration Testers
Generate MD5/SHA hashes of known strings for hash comparison and dictionary attack validation in controlled environments.
Students & Educators
Learn how cryptographic hash functions work through the Bcrypt Hash Explainer and compare MD5 vs SHA output characteristics.
Sysadmins
Generate secure random passwords for service accounts, API keys, and configuration files without leaving the browser.
Tech Teams
Standardise hash algorithm usage across projects by testing MD5, SHA-256, and HMAC side by side before implementation.
