Function hash_password 

pub fn hash_password(password: &str) -> Result<String>

Hashes a password using bcrypt with a secure cost factor.

This function uses the bcrypt algorithm to hash passwords with a predefined cost factor. Bcrypt is designed to be computationally expensive to prevent brute-force attacks and includes automatic salt generation.

Arguments

• password - The plaintext password to hash

Returns

• Ok(String) - The bcrypt hash including salt and cost parameters
• Err(AuthError) - If hashing fails or password is invalid

Security Notes

• Uses bcrypt’s default cost factor (currently 12)
• Each hash includes a unique random salt
• The same password will produce different hashes due to random salting
• Empty passwords are rejected for security

Example

use auth_framework::secure_utils::hash_password;

let password = "user_password_123";
let hash = hash_password(password).unwrap();
println!("Password hash: {}", hash);
