Security helpers for builders and analysts
Roll passwords, verify cryptographic hashes, and validate JWT claims without leaving the browser. These tools keep secrets local while giving you full visibility into authentication and integrity checks.
Bring them up alongside production logs to inspect payloads, check signatures, or educate teammates on hashing best practices—all without uploading anything to a server.
What this category includes
Security workflows depend on quick spot checks: verifying a file hash, generating a one-off password, or decoding a JWT to confirm expiration. This toolkit keeps those tasks one click away. Generate cryptographically strong passwords, compute MD5/SHA hashes, inspect JSON Web Tokens, and walk through encoding best practices.
Every tool is 100% client-side, so secrets, payloads, and credentials never leave your session. Use them to double-check deployment artifacts, audit API responses, or train teams on proper hashing and encoding techniques. The list below covers both foundational hashing utilities and user-friendly helpers like password strength tests and secure generators.

Read guide →Frequently asked questions
Q1
Are the password generator and hash tools secure?
Yes. They use the browser’s cryptographically secure random generator and run entirely client-side, so generated passwords and hashed inputs never touch our servers.
Q2
Which hash algorithm should I pick?
Use SHA-256 or SHA-512 for verifying artifacts and security workflows. MD5 and SHA-1 remain helpful for legacy checksums but are not collision resistant for new systems.
Q3
Can I inspect JWT tokens safely?
Absolutely. Paste the token into the JWT Decoder to view header and payload claims instantly. Since decoding happens locally, no tokens are transmitted externally.
Q4
Do you store any of the generated passwords?
No. Everything is generated in-memory within your browser tab. Close the tab and the generated values disappear with it.
