How to Hash and Salt Password in C?

When it comes to securely storing passwords in C, hashing and salting are essential techniques to protect user data from potential breaches. Hashing involves converting a password into a fixed-length string of characters using an algorithm. Salting adds an extra layer of security by appending a unique value to each password before hashing.

To hash and salt a password in C, you can follow these steps:

1. Include the 'openssl/sha.h' header file for using SHA hashing algorithm.
2. Generate a random salt value using a secure random number generator.
3. Combine the password with the salt value.
4. Hash the combined password and salt using the chosen hashing algorithm.
5. Store the hashed password along with the salt value securely in your database.

Implementing hashing and salting in C requires careful consideration of security best practices. It is crucial to choose a strong hashing algorithm, such as SHA-256, and ensure that the salt value is unique for each password.
