CSR generator

Generates a new private key and a matching certificate signing request. Copy both immediately — the key is shown once and is not stored on this server.

What is CSR generator?

A Certificate Signing Request (CSR) is what you submit to a certificate authority to get a TLS certificate issued — it contains your domain name and public key, generated alongside a private key that must stay secret.

How to use it

Fill in the domain (and any additional domains as SANs) plus organization details, and generate — both the private key and CSR are shown once, since neither is stored on the server.

Example

A CSR for example.com with SAN www.example.com is ready to submit to any CA, alongside its newly-generated private key.
