The passwords in my config are in clear text? That’s because there are three levels of password storage 0 (not encrypted), 7 (weakly encrypted), and (5 strongly encrypted). Online since November 2008, Last update: 03/nov/2009, Contact:. So whats the point of these type 7 passwords? Well the only real benefit of them is if someone is looking over your shoulder while you are looking at the config, they can’t see actual passwords in the config. This page allows you to decrypt Juniper 9 passwords and Cisco 7 passwords. Password type 0 and type 7 are deprecated. Petes-Router(config)# no key chain decrypt Send lifetime (always valid) - (always valid) This command obscures all clear-text passwords in the. Key 0 - text " lifetime (always valid) - (always valid) The first method of encryption that Cisco provides is through the command service password-encryption. Passwords are combined with a random salt value and have a one-way MD5. *Mar 1 00:04:48.691: %SYS-5-CONFIG_I: Configured from console by console If you search your favorite search engine for Cisco type 7 decrypt you will. If the hash is to be reconstructed to an existing type 8 hashed password, simply use the corresponding salt instead of the freshly generated salt (as in the first part of the answer).Enter configuration commands, one per line. Print("$8$%s$%s" %(salt, hash)) # concatenate 8 prefix, salt and Base64 encoded PBKDF2 hash Hash = type8Hash(salt.encode('ascii'), password) # calculate Base64 encoded PBKDF2 hash When service password-encryption is configured into a cisco router and the. Copy and paste only the portion bolded in the example. Type 7 passwords appears as follows in an IOS configuration file. Salt = b64CiscoEncode(os.urandom(10)) # create random 10 bytes (=80 bits) salt and Base64 encode Anything that looks like a type 7 encrypted string gets decrypted. Paste any Cisco IOS 'type 7' password string into the form below to retrieve the plaintext value. Type 7 is a password with a weak, exclusive-or type encryption. The type 8 hashed password is the concatenation of 8-prefix, salt and Base64 encoded PBKDF2 hash: import hashlib This document describes the Enhanced Password Security feature in Cisco IOS Release. over to the pre-master secret Cisco type 7 password decrypt hack crack. Which successfully reproduces the hashes from the linked example.Ĭoncerning your comment: The salt is produced by randomly generating 10 bytes (= 80 bits) that are Base64 encoded (using the Cisco alphabet), resulting in 14 bytes. Existing and newly created plaintext passwords are then stored in Type 6 format. Print(type8Hash(b'dsYGNam3K1SIJO', b'cisco')) # 7nv/35M/qr6t.dVc7UY9zrJDWRVqncHub1PE9UlMQFs # $8$dsYGNam3K1SIJO$7nv/35M/qr6t.dVc7UY9zrJDWRVqncHub1PE9UlMQFs Print(type8Hash(b'mTj4RZG8N9ZDOk', b'cisco')) # elY/asfm8kD3iDmkBe3hD2r4xcA/0oWS5V3os.O91u. Return b64CiscoEncode(hashlib.pbkdf2_hmac('sha256', password, salt, 20000)) Return base64.b64encode(data).decode('ascii').translate(TRANS).rstrip('=') TRANS = str.maketrans(STD_B64_ALPHABET, CISCO_B64_ALPHABET) STD_B64_ALPHABET = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'ĬISCO_B64_ALPHABET = './0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz' ), which are eventually confirmed by the successful tests.Ī possible Python implementation is: import hashlib While the iteration count is described here, the others are more or less educated guesses (e.g./0-9A-Za-z is a common variant with the letter. The hash values from the linked example can be reproduced if the following is considered in addition to the information given there: privilege exec level 7 configure terminal privilege exec level 7 configure privilege exec level 7 show running-config privilege exec level 7 show privilege level 15 privilege level 15 Now that the ' My ' user can change the IP address of the interface, but still no output when i show running-config.
