(MFC) Generate RSA Key for SFTP

See more SSH Key Examples

Generates an 2048-bit RSA key for SSH/SFTP. Your application will use the generated private key. The public key is to be uploaded to the server and stored in the ".ssh" directory located under the HOME directory of the SSH/SFTP user account.
