Cisco devices encrypt standard user accounts with a notoriously weak encryption algorithm. If you are able to obtain the plaintext configuration file to a device, you'll probably see a string like the one below somewhere.
username jdoe password 7 07362E590E1B1C041B1E124C0A2F2E206832752E1A01134D
Here we have the definition of an account with the username of "jdoe" and a Cisco 7 encrypted password string of 07362E590E1B1C041B1E124C0A2F2E206832752E1A01134D. By copying that string into the "Encrypted" field below and clicking "Decrypt", you can see it's plaintext form.
