Review Common Name, Organization, Country, and Key Algorithm.
Confirm details before submitting to Let's Encrypt or DigiCert.
A CSR (Certificate Signing Request) is a block of encoded text given to a Certificate Authority when applying for an SSL/TLS certificate.
No, a CSR contains only the public key and applicant metadata.
