Security Tools
Hash, sign, inspect tokens, and generate passwords in the browser.
Focused security utilities for developer review
This security hub keeps content centered on practical, source-backed developer workflows. Each highlighted tool has a matching guide or standards reference and a clear privacy promise.
Workflow focus
- Use Hash Generator for file fingerprints and SHA-family comparisons.
- Use HMAC Generator for webhook and API signature checks.
- Use Bcrypt Hash when explaining password storage and cost factors.
- Use JWT Decoder to inspect token structure without sending tokens to a server.
- Use Password Generator when a strong unique credential is needed.
Use case first
Each hub starts with the artifact you already have — payload, file, token, signature, address, or unit value — then points to the smallest useful tool.
Browser-side processing
The highlighted tools are designed for local inspection. Use test data or redacted samples when the value is a secret, token, private key, or customer record.
Guide connection
Related articles explain standards, edge cases, and common mistakes before you rely on a transformation in production.
Featured tools
Focused security tools for hashing, HMAC signatures, bcrypt password hashes, JWT decoding, and password generation. All processing runs in your browser.
Tools in this workflow
5 toolsHash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, SHA-512 hashes from text with real-time computation.
Developer toolHMAC Generator
Generate HMAC signatures using SHA-256, SHA-384, SHA-512 with a secret key.
Developer toolBcrypt Hash
Generate and verify bcrypt password hashes with configurable rounds.
Developer toolJWT Decoder
Decode JSON Web Tokens to inspect header, payload, signature, and expiration time.
Developer toolPassword Generator
Create strong, secure passwords with customizable options and strength indicators.
How to choose
Start with the data or artifact you already have, then pick the tool that performs the smallest useful transformation. Formatter and validator pages are best for inspection; converter pages are best when you need a new output format; security utilities are best for local verification and debugging.
Safety notes
Featured tools run in the browser, but sensitive values still deserve care. Use redacted samples in screenshots and support requests, avoid sharing API secrets or private keys, and check the related guide before relying on a result in production.
Documentation checklist
A useful developer tool page should explain the input format, the output format, common mistakes, privacy handling, and when another tool is a better fit. The featured tools on this hub are selected because they can be documented clearly against those checks.
If a workflow needs a broader catalog, start from Browse All Tools. If you need the reasoning behind a format or security choice, start from the Guide Index.

Frequently asked questions
Are these security tools safe for sensitive data?
The highlighted tools run in the browser. Password candidates, JWTs, HMAC secrets, and hash input are not uploaded to BeautiCode servers.
Why focus on hash, HMAC, bcrypt, JWT, and passwords?
These tools map directly to common developer workflows: file fingerprints, webhook signatures, password storage, token inspection, and credential generation.
Are these tools a replacement for production key management?
No. They are for inspection, debugging, local verification, and education. Production secrets should still live in a proper KMS, HSM, or secrets manager.
