Password salting is a cryptographic technique utilized in safeguarding passwords by appending a string of characters, known as a “salt,” to the user’s password before hashing. This method ensures that even if two users have the same password, their hashes will differ due to the unique salts. The procedure significantly enhances the security of stored passwords against brute-force and rainbow table attacks.
The History of the Origin of Password Salting and the First Mention of It
The practice of password salting emerged in the early days of UNIX operating systems. Robert Morris introduced salting in UNIX Version 3, released in 1979, to bolster the security of password hashes. By implementing this simple yet powerful concept, the security of passwords stored in the shadow file was considerably heightened, leading to its widespread adoption in various systems.
Detailed Information About Password Salting. Expanding the Topic Password Salting
Password salting mitigates risks associated with brute-force and rainbow table attacks. Here’s a detailed look into the process:
- Generation of Salt: A random string is generated as a “salt.”
- Concatenation: The salt is added to the user’s password.
- Hashing: The concatenated string is then hashed using a cryptographic hash function.
- Storing: Both the salt and the hash are stored in the database.
Every time a user logs in, the process is repeated, and the stored hash is compared with the computed hash.
The Internal Structure of the Password Salting. How the Password Salting Works
- User Input: The user enters their password.
- Retrieve Salt: The system retrieves the stored salt for that user.
- Concatenate and Hash: The system concatenates the password and salt, hashes the result.
- Verify: The hashed result is compared with the stored hash.
Analysis of the Key Features of Password Salting
- Uniqueness: Even if users share the same password, the hashes will differ.
- Resistance to Rainbow Tables: Makes precomputed hash tables (rainbow tables) ineffective.
- Enhanced Security: Increases the complexity of brute-force attacks.
Types of Password Salting. Use Tables and Lists to Write
| Method | Description |
|---|---|
| Cryptographic Salt | Utilizes a cryptographic algorithm to generate the salt. |
| Peppering | Combines a secret key or “pepper” with the salt, stored separately from the hashed password. |
| Adaptive Salting | Adjusts the salt value based on user or system properties for further uniqueness. |
Ways to Use Password Salting, Problems, and Their Solutions Related to the Use
Usage:
- Web Applications: For securing user passwords.
- Databases: To protect stored credentials.
Problems and Solutions:
- Insufficient Salt Length: Use a sufficiently long salt.
- Reuse of Salts: Always generate unique salts for each user.
