How Does WordPress Secure User Passwords with Hashing?

Exploring WordPress Password Hashing

WordPress employs a robust password hashing mechanism to safeguard user credentials. Let's delve into the details:

The WordPress Password Hasher

WordPress utilizes the Portable PHP password hashing framework, widely adopted in content management systems like Drupal and Joomla. This framework offers advanced encryption algorithms to generate secure password hashes.

Evolution of Hashing

Earlier versions of WordPress relied on MD5 for password encryption. However, its inherent weaknesses led to the adoption of more secure hashing algorithms.

Understanding WordPress Hash Format

The example hash provided ($P$Bp.ZDNMM98mGNxCtHSkc1DqdRPXeoR.) is in the following format:

• $P$: Identifier denoting Portable PHP password hashing framework
• Bp: Algorithm used (bcrypt)
• ZDNMM98mGNxCtHSkc1DqdRPXeoR: The actual hash

bcrypt Algorithm

bcrypt is a computationally intensive hashing algorithm that generates highly secure hashes. It incorporates a salt to further enhance security, making brute-force attacks impractical.

Hash Generation

To generate a hash using bcrypt, you can visit http://scriptserver.mainframe8.com/wordpress_password_hasher.php. This tool allows you to create secure hashes for use with WordPress.

By leveraging the Portable PHP password hashing framework and robust algorithms like bcrypt, WordPress effectively protects user passwords from unauthorized access and prevents malicious attacks.
