Cryptographic salts are broadly used in many modern computer systems, from Unixsystem credentials to Internet security. Salts are closely related to the concept of a cryptographic nonce. Example usage[edit] Here is an incomplete example of a salt value for storing passwords. This first table has two … See more In cryptography, a salt is random data that is used as an additional input to a one-way function that hashes data, a password or passphrase. Salts are used to safeguard passwords in storage. Historically, only the output from an … See more 1970s–1980s Earlier versions of Unix used a password file /etc/passwd to store the hashes of salted passwords … See more • Password cracking • Cryptographic nonce • Initialization vector • Padding See more • Wille, Christoph (2004-01-05). "Storing Passwords - done right!". • OWASP Cryptographic Cheat Sheet • how to encrypt user passwords See more Salt re-use Using the same salt for all passwords is dangerous because a precomputed table which simply … See more To understand the difference between cracking a single password and a set of them, consider a file with users and their hashed passwords. Say the file is unsalted. Then an … See more It is common for a web application to store in a database the hash value of a user's password. Without a salt, a successful SQL injection attack may yield easily crackable passwords.
