What is Cisco password types & best practices?
The “Cisco Password Types: Best Practices” Cybersecurity Information Sheet analyzes Cisco’s wide variety of password encryption and hashing schemes to secure passwords stored in configuration files. NSA provides recommendations based on each password type and best practices to help administrators secure sensitive credentials.
What is a Cisco type 6 password?
Cisco Type 6 passwords, for example, allow for secure, encrypted storage of plaintext passwords on the device. When configuration files are not properly protected, Cisco devices that are configured to use a weak password protection algorithm do not adequately secure the credentials.
How do I encrypt a password?
To use Type 6 or convert existing password types (Type 0 or Type 7) to Type 6, configure the primary key with the “key config-key password-encrypt” command. This key is not saved in the running configuration file and is used to encrypt and decrypt the passwords. Then enable AES encryption by issuing the "password encryption aes" command.
Introduction
This document describes the security model behind Cisco password encryption, and the security limitations of that encryption. cisco.com
Background
A non-Cisco source has released a program to decrypt user passwords (and other passwords) in Cisco configuration files. The program does not decrypt passwords set with the enable secretcommand. The unexpected concern that program caused among Cisco users has led to the suspicion that many users rely on Cisco password encryption for more security th

Requirements There are no specific requirements for this document. Components Used This document is not restricted to specific software and hardware versions. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration.

User Passwords
User passwords, and most other passwords (not enable secrets) in Cisco IOS configuration files, are encrypted with a scheme that is very weak by modern cryptographic standards. Although Cisco does not distribute a decryption program, at least two different decryption programs for Cisco IOS passwords are available to the public on the internet; the
Configuration Files
When you send configuration information in e-mail, sanitize the configuration from type 7 passwords. You can use the show tech-support command, which sanitizes the information by default. Sample show tech-supportcommand output is shown here: When you save your configuration files on a Trivial File Transfer Protocol (TFTP) server, change the privile
Can The Algorithm Be Changed?
Cisco has no immediate plans to support a stronger encryption algorithm for Cisco IOS user passwords. If Cisco does decide to introduce such a feature in the future, that feature definitely imposes an additional administrative burden on users who choose to take advantage of it. It is not, in the general case, possible to switch user passwords over
