1024 | rsa-2048}
Select how to validate a client accessing a HTTPS website using RSA
encryption through the Zyxel Device. The Zyxel Device must check that the
client’s certificate and public key are valid and were issued by a
Certificate Authority (CA) listed in the Zyxel Device's list of trusted CAs. The
default value is 1024.

changing the server signing mode.
ssl-inspection server-sign-
cert mode {ecdsa-rsa-
1024|ecdsa-rsa-2048}
Select how to validate a client accessing a HTTPS website using ECDSA
encryption through the Zyxel Device. ECDSA is required by certain clients
such as iOS 13.
•
ecdsa-rsa-1024 means the Zyxel Device uses ECDSA-256 if the
client supports ECDSA-256, or RSA-1024 if the client does not support
ECDSA-256.
•
ecdsa-rsa-2048 means the Zyxel Device uses ECDSA-256 if the
client supports ECDSA-256, or RSA-2048 if the client does not support
ECDSA-256.
