PEM Generator

Generate a random PEM-format block for tests and fixtures. Wraps cryptographically random bytes in standard -----BEGIN/END----- armor. Synthetic placeholder data — not a usable private key.

Also known as: token generator · api token generator · secret token · bearer token

Private by design. Your token is generated locally and never saved, uploaded, or shared — only your settings can be, and only when you choose.

Presets

Hex, alphanumeric, URL-safe, and custom modes use output characters. Base64 and base64url use random bytes before encoding.

Optional text to prepend to every token, such as sk_ or tok_.

PEM wraps random bytes in standard armor for test fixtures — not a real key.
