What is the CSR & RSA Key Generator?
A form that builds a PKCS#10 Certificate Signing Request (CSR) together with its matching RSA private key, both generated locally in the browser so the private key is never transmitted anywhere.
How it works
Using node-forge, it first generates an RSA key pair (2048 or 4096-bit, your choice), then encodes the distinguished name fields you entered — common name, organization, locality, country — into the CSR's ASN.1 structure, signs it with the new private key using SHA-256, and outputs both as PEM text you can copy or download.
SysAdmin & security use cases
- Preparing a CSR to submit to a Certificate Authority like DigiCert or Let's Encrypt
- Generating a CSR on a machine that doesn't have OpenSSL installed
- Creating throwaway certificates for a local dev or staging environment
- Producing CSRs with a consistent organization name across several servers
