(usually a bad idea), and a ‘ ’ entry (eg. ::) indicates a password is not required to log in Username: a direct match to the username in the /etc/passwd file.

On most Linux systems, only the root account has the ability to read the etc/shadow has more restrictive permissions than the etc/passwd stores user accounts, and the /etc/shadow stores the information about user accountsĪnd the encrypted password hashes. The users’ information and passwords in Linux and UNIX operating system are stored in files. Cryptographic hash functions are used to implement password hashing.There are multiplecryptographic hash functions, such as MD5, SHA-2.įor example, the following are the MD5 hash codes of different strings. The unique feature of hash functions is that any change in input data will result in a completely different hash code. The fixed-length “fingerprint” is called a hash value or hash code. Password HashingĪ hash function turns any amount of data into a fixed-length “fingerprint” that cannot be reversed. Understand what password hash is and how password hash be cracked.

Hackers can get immediate access to them if they break into the system. If users’ passwords are stored in a database as plain text, malicious
