Random Number Generator
Use this privacy and security utility to generate, inspect, encode, decode, or verify sensitive data directly in your browser.
Privacy note: Security-sensitive tools are designed for local browser use, but you should only handle secrets on a device and browser profile you trust.
Limitations: Your clipboard, browser extensions, screen sharing, and device security can still expose values you copy or display.

Use privacy tools only on a trusted device. Clipboard history, browser extensions, and screen sharing can still expose copied values.

Enter the values, files, tokens, or generator settings needed for the task.
Toolkit processes the result locally in your browser and shows copyable output or a downloadable file when available.
Privacy
Security-sensitive tools are designed for local browser use, but you should only handle secrets on a device and browser profile you trust.
Limitations
- Your clipboard, browser extensions, screen sharing, and device security can still expose values you copy or display.
- Hashing and checksum tools verify equality or integrity, but they do not prove a file is safe or malware-free.
- Do not rely on generated or decoded values until you have checked the requirements of the system where they will be used.
FAQs
Do these tools upload my secrets or files?
Supported privacy tools run in your browser and do not need an account.
Can I paste production secrets?
Avoid pasting production secrets unless you are on a trusted device and browser profile with no untrusted extensions.
Are checksums the same as encryption?
No. Checksums and hashes help compare data, but they do not hide the original file or text.
Why are bcrypt and MD5 not included here?
This browser-only set focuses on currently available local Web Crypto and safe client-side utilities. Bcrypt needs a dedicated browser library, and MD5 is a legacy hash not supported by Web Crypto.
