Additional Commands and References
After Cisco IOS IPS loads the signature package into memory, it starts reading signatures and
attempts to build them according to the configuration. An error message such as:
%IPS-3-INVALID_DIGITAL_SIGNATURE: Invalid Digital Signature found (key not found)
means the public crypto key is invalid. Refer to "Configuring Cisco IOS IPS Crypto Key" (Step 3) to
reconfigure the public crypto key.
