What is a Type 5 password?

Cisco type 5 password This password type was introduced around 1992 and it is essentially a 1,000 iteration of MD5 hash with salt. The salt is 4 characters long (32 bits).

What is secret 5?

The “5” tells the router that you are pasting an already encrypted password (md5 hash)… It is a way for you to transfer an encrypted password to another device. 0 Specifies an UNENCRYPTED password will follow. 5 Specifies an ENCRYPTED secret will follow. LINE The UNENCRYPTED (cleartext) ‘enable’ secret.

What is a Type 7 password?

Type 7 passwords use a very weak algorithm that can be easily reversed, but the “secret” command utilizes a MD5 hash which is much more secure. Due to this, it is never a good idea to use Type 7 passwords. This policy applies to both user accounts and passwords applied to the VTY or Console lines.

What is type 8 password?

Type 8 passwords are hashed with the Password- Based Key Derivation Function version 2 (PBKDF2), SHA-256, an 80-bit salt, and 20,000 iterations, which makes it more secure in comparison to the previous password types. The passwords are stored as hashes within the configuration file.

What type of encryption is used with a type 5 encrypted password in a cisco router configuration?

salted MD5 hashing algorithm
Type 5. These use a salted MD5 hashing algorithm. These should only be used if Type 6, 8, or 9 is not available on the IOS version you are running.

Which password types are encrypted?

This is adequate for passwords, messages, corporate information and the like. It is not secure enough for government encryption, according to the standards they use. However, if you choose to use any of 10 pre-designated keys (which makes it level 5), it is probably AS SECURE as government encryption in most cases.

What is the password decryption of a password?

There is no decryption as the passwords are not encrypted but hashed. Although it’s also a cryptographic operation, it’s not a reversible encryption but a one-way function.

Should I use MD5 to encrypt passwords?

If you still want to use md5 to encrypt passwords on your website, good thing would be to use a “salt” to make the hash more difficult to crack via bruteforce and rainbow tables. A salt is simply a caracters string that you add to an user password to make it less breakable.
