Syntax
crypto rsa-keygen modulus { 1024 | 2048 | 4096 | 512 }
Usage
Generate an RSA key pair and Certificate Signing Request (CSR) using information to authenticate the site.
You can specify the modulus (key size of the generated certificate) as 512. 1024, 2048 or 4096 bits.
A CSR is a message sent to a Certification Authority (CA) to request a public key certificate for an entity,
where the entity is the subject of the certificate. The software creating the CSR must first generate an RSA
key pair; the key pair comprises a public and private key. The public key is bundled with the subject's name,
and other information to form the CSR.
