Generate cryptographically strong random secrets for JWT signing. Choose between 8 and 512 bits. Everything runs locally in your browser using the secure crypto API.
This tool uses crypto.getRandomValues() to produce a cryptographically secure secret key, ideal for JWT signing or HMAC operations. The output is Base64-encoded for compatibility with most libraries.
Remember: JWT secrets must remain private. Never share or commit them to source control.
The JWT Secret Key Generator creates secure Base64 keys ideal for signing JWTs or other HMAC-based operations. Choose a strength between 8 and 512 bits depending on your security needs.
Everything happens client-side using the Web Crypto API — your keys never leave your browser. Masked view keeps secrets safe during sharing or presentations.
