Generate secure API keys with configurable length, prefixes, separators, and character sets.
Uses secure browser randomness. Press Ctrl/Cmd + Enter to generate.
| Metric | Value |

Privacy: generation runs locally in your browser. No API keys are stored or transmitted.
How it works
Choose the random length, optional prefix, and character sets. The tool uses crypto.getRandomValues() to generate secure random characters locally in your browser.
Examples
- pk_live_ + 32 random chars → typical public/private key style prefix
- sk_test_ + grouped output → easier visual scanning during development
- 64-char key with letters and numbers → higher entropy output
