a. Key Strength
Key Strength is the initial RSA Key Strength which may be 512, 1024, and 2048 bits. The
higher the strength, the slower the initial connection with ISY (up to 10 seconds for 2048
bits). Please note that once the initial connection has been established, then this parameter
no longer plays a role and communication and cryptographic methods are then based on
the strength of the chosen cipher suite’s symmetric key.
Note: Although ISY supports 512, 1024, and 2048 bits for self-signed certificates, however
– and in case of certificate requests – the strength is subject to the approval of the
certificate authority. In most cases, the lowest key strength approved by certificate
authorities is 2048.
b. Import Cert.
If you have a PKCS12 (pfx) format file which includes both the Certificate as well as the
Private Key, then choose this option to import your certificate/key combination into ISY.
You will need to use this feature if you intend to use a preexisting certificate (including
wildcard certificates).
Once imported successfully, ISY will reboot for the changes to take effect.
