![]() ![]() ![]() ![]() Even though it was encrypted using SHA256 there was no salt used leaving it vulnerable to brute force attacks. In the configuration file this would be shown as: enable secret 5 $1$B8pH$PmmcMRoqfeEtQ7WxL865a0Īdditional types of encryption were used, including type 4 that was found to have a number of flaws. There are scripts on Github to decode this format or you could use the form above to quickly decode a type 7 password.Ī very common example, that provided significantly more security than the Cisco Type 7 encoding is to use MD5 with a Salt. The Cisco Type 7 password format uses a simple reversible cipher (). You can see that while the password is obfuscated getting the password for this device would not be difficult at all. Here is an example of a password of type 7: enable password 7 094F4F1D1A0DDD When looking at a Cisco Configuration file you can easily spot the type of security used with the password by looking for the enable line. It simply sits in the configuration in plain text. There is no obsfucation or hashing of the password. In this example we can see a type 0 password configuration. From type 0 which is password in plain text up to the latest type 8 and type 9 Cisco password storage types. Over time Cisco has improved the security of its password storage within the standard Cisco Configuration. ![]()
