Number one reason you shouldn't paste your Cisco configs or password hashes on the Internet:
Cisco's PIX password encryption is a base64 encoded MD5 hashsum, using only one MD5 update (no salting or anything). This also permits for cryptanalysis attacks using rainbow tables to speed up the process.
Simple hashes like:

'5' means that the clear password has been converted to cisco password type 5. Type 5 password is a MD5 based algorithm (but I can't tell you how to compute it, sorry). Type 7 that is used when you do a 'enable password' is a well know reversible algorithm. 'service password-encryption' just ensure that password will not be stored in clear (type 0). Look for a program called tomas.exe aka Too Many Secrets - this one does work for the cisco passwords.

Also, note that MD5 has know weaknesses in the algorithm, that may allow for more complex password cracking attacks.
Also, if you're using a 'type 7' password, that's pretty much useless, since it can get cracked instantly. People can just use simple tools such as Cain and Abel, or Solarwinds Router Password Decryption to reverse the crypto on type 7 passwords.

IOS type 5 passwords (MD5 using 1000 rounds) is more complex, and harder to crack, but yous still shouldn't paste your hashes for everyone to see. Remember, even with type 5 passwords, you're still vulnerable to dictionary attacks, hybrid attacks, rainbow table attacks (PIX only), md5 repository attacks, or plain old password guessing.
If you're going to paste your config files anywhere, use the 'show tech-support' command available in newer IOS versions. It gives more info, and strips confidential information, password hashes and such.

I was updating my Cisco cracking tool, cisco_pwdecrypt by adding the Cisco “Type 5” password and I thought it would be interesting to show you how to do it with Python. A vce player for windows.

Cisco ‘Type 5’ Passwords

Mostly known as MD5 Crypt on FreeBSD, this algorithm is widely used on Unix systems. As Cisco uses the same FreeBSD crypto libraries on his IOS operating system, the “type 5” hash format and algorithm are identical. The only exception would be that Cisco requires 4 salt characters instead of the full 8 characters used by most systems.

As a demonstration, here are the differences between Cisco’s hash and original FreeBSD’s hash:

Here is a breakdown of the hash:

Requirements

Be sure to prepare your environment first:

• Install Python3
• Install the passlib module ($ pip install passlib)

You can use any IDE ot text editor to build your Python script. I personally use Pycharm.

Generating a Type 5 Password

Crack Cisco Ios Password 5

cities skylines mac download reddit The passlib will help us to quickly generate a “type 5” hash. Let’s do a try with the following code:

You can even set your own salt to generate the hash.

Cracking a Type 5 Password

To crack a hash, we’ll use the verify() method from the passlib module. Let’s set a dictionary to try to find the password corresponding to the following hash: “$1$VkQd$Vma3sR7B1LL.v5lgy1NYc/”.

Cisco Password Decrypt

We found the password ! Easy, isn’t it ?

Conclusion

Crack Cisco Enable Password 5

This code has been implemented in cisco_pwdecrypt. You should read the source code (as always) to have more detailed explanation and maybe enhance it !
