Hi team,
I am looking to encrypt the radius shared key as the type 7 Cisco encryption is easily breakable. I have found that Cisco devices only allow Type 0 or type 7 encryption for Radius Shared key. You can specify that the key-value is in clear text (0) format or is encrypted (7). The default format is clear text. The maximum length is 63 characters. The share key password is highly recommended to be alphanumerical, have at least one upper case letter and include symbols/characters. The longer and more complex the password, the more secure it will be.
Is there any possible way to increase the complexity or the algorithm to secure the key to ensure it is not easily breakable?
Thank you in advance for your help.
Carlos
