A Certificate Signing Request for an SSL Certificate can be created using the controls on the Certificates & Security > Generate CSR UI page. By default, CSRs generated by LoadMaster request an RSA-encrypted key. If you enable the Generate Elliptic Curve Request option on this page, LoadMaster instead requests an ECC (elliptic curve) key. Smaller ECC key sizes generally provide the same cryptographic strength as much larger RSA key sizes; and, so ECC keys are becoming increasingly common because of both the reduced storage footprint as well as processing resources required.
