Convert CSR to KEY

Can you convert CSR to KEY?
QUICK ANSWER
Is it possible to convert CSR to KEY?
No - not a direct conversion.

You cannot extract the private key from a CSR - the CSR contains only the PUBLIC key. The private key was created alongside the CSR and saved separately; if you lost it, you must generate a new key pair and a new CSR.

No direct path
Also to KEY: PFX · PEM · P12
