Cryptographically Secure Hashing with PBKDF2
PBKDF2 (Password-Based Key Derivation Function 2) is a standard for secure password hashing. It applies a pseudo-random function to the password along with a salt many times, making brute-force attacks significantly more difficult.

Breakdown
1
new Rfc2898DeriveBytes(password, salt, 100000, ...)
Initializes the hashing algorithm with 100,000 iterations for security.
2
pbkdf2.GetBytes(32);
Generates a 32-byte hash from the derived key.
