Revealing the Type-7 Encoded Information from the Configuration without Using External Tools

Revealing the Type-7 Encoded Information from the Configuration without Using External Tools

To view the unencrypted password 7 hash of a pre-shared key, use the “do show key chain command” from config mode.

IE:

Router(config)#key chain LIGHT
 Router(config-keychain)#key 718
 Router(config-keychain-key)#key-string 7 11192616193C233850012E3D2B2725711D
 Router(config-keychain-key)#do show key chain LIGHT Key-chain decrypt:
 key 1 -- text "decrypted_password"
 accept lifetime (always valid) - (always valid) [valid now]
 send lifetime (always valid) - (always valid) [valid now]
