How to Decrypt Hash Password in Laravel: Quick Guide & Tips

Although covering any kind of security algorithm is tempting, the simple answer to this query is “No”. You can’t “decrypt” a hash password because it’s designed as such.

Storing passwords in plain text is a recipe for disaster, leaving them vulnerable to breaches and unauthorized access. Hashing, on the other hand, provides an impenetrable layer of protection. It’s used alongside the best Laravel security practices to ensure the site data and passwords are protected at all times.

Our Laravel development services encounter the query on decrypting hash passwords quite often. So I have created this blog to clarify the misconception of decryption. Let’s begin with what hashing is.

What is Password Hashing?

process of password hashing in laravel

Password hashing is a crucial security measure implemented in Laravel and many other web frameworks. Storing user passwords in plain text would be a major security risk. So hashing transforms them into a unique, unreadable string of characters. This string, called a “hash,” acts as a secure representation of the original password.

Here’s the key point.

Hashing is a one-way process. While it’s easy to generate a hash from a password, it’s computationally impossible to reverse the process and retrieve the original password from the hash. This ensures that even if a hacker gains access to your database, they cannot easily decipher the actual passwords stored within.

That’s why the Laravel experts advise on using this tactic as a form of data protection in the websites.

How Does Hashing Work in Laravel?

Laravel takes a secure approach to password storage by utilizing hashing algorithms, primarily Bcrypt and Argon2. These algorithms work their magic behind the scenes, transforming plain-text passwords into seemingly random strings called “hashes.” Here’s a breakdown of the process:

  1. Password Input: When a user registers or changes their password, Laravel receives the plain-text password.
  2. Salt Generation: A random “salt” is generated, which acts as an additional layer of security by being uniquely combined with the password before hashing.
  3. Hashing Algorithm: The chosen algorithm (Bcrypt by default) takes the password and salt and applies a complex mathematical func. that produces a unique hash. This hash is a one-way transformation, so it’s impossible to derive the original password from it.
  4. Secure Storage: The generated hash, not the original password, is stored in the database.

This process ensures that even if an attacker gains access to the database, they wouldn’t be able to decipher the actual passwords. That improves the site’s security significantly.

Is It Possible to Decrypt a Hash Password in Laravel?

No, it is not possible to decrypt a hash password in Laravel, or any other system that employs proper hashing techniques. Remember, passwords are hashed, not encrypted. This crucial distinction lies in the nature of the transformation:

  • Encryption: Encryption is a reversible process where data is scrambled using a key. With the correct key, the original data can be retrieved.
  • Hashing: Hashing is a one-way function. It takes data (the password) and produces a unique “hash” that acts as a fingerprint. There’s no mathematical process to reverse this operation and obtain the original password.

Even if someone gains access to the stored hash values in your database, they can’t decipher the actual passwords.

How to Decrypt a Hash Password in Laravel?

Again, let me make it clear that decrypting hashed passwords in Laravel is not possible. However, Laravel provides functionalities for managing password security. Here are the relevant methods.

Using Hash::make() Method

This method is crucial for securely storing passwords. It takes the plain-text password as input and generates a unique hash using a chosen hashing algorithm (Bcrypt by default). This hash is then stored in the database, not the original password. Here’s an example:

$password = 'mySecretPassword';
$hashedPassword = Hash::make($password);

Using Hash::check() Method

This method is used during login attempts. It takes the entered password and compares it to the stored hash. It utilizes the same hashing algorithm and salt used during password creation to generate a new hash from the provided password. If the newly generated hash matches the stored one, the login is successful.

$enteredPassword = request('password');
if (Hash::check($enteredPassword, $hashedPassword)) {
    // Login successful
} else {
    // Login failed

Using Hash::needsRehash() Method

Hashing algorithms are constantly evolving to improve security. This method checks if the stored hash requires updating with a more secure algorithm due to advancements. If necessary, it automatically re-hashes the password using the latest algorithm, enhancing overall security.

if (Hash::needsRehash($hashedPassword)) {
    $hashedPassword = Hash::make($hashedPassword);
    // Update the stored hash with the newly generated one

Remember, these methods focus on secure password management through hashing and verification. You can’t retrieve the original password in plain text.

So if you want help with decrypting hash passwords on your Laravel website, you can consult with our Laravel development experts.

Alternatives to Decrypting Hash Passwords in Laravel

If you’re not comfortable with decrypting hash passwords in Laravel, there are some alternative approaches. These include resetting the password through secure procedures or utilizing reputable third-party decryption tools. These methods can handle some specific decryption requirements.

Password Reset Mechanism

Instead of attempting to retrieve the original password, Laravel provides a robust password reset mechanism. This allows users to initiate a password reset process by providing their registered email address. Laravel sends a secure token to the user’s email, which they can use to set a new password. This approach ensures that even if an attacker gains access to the hashed passwords, they cannot access accounts without the user’s knowledge.

Secure Password Storage

Laravel utilizes strong hashing algorithms like Bcrypt and Argon2 to store passwords. These algorithms add significant layers of security, making it computationally impractical for attackers to crack the hashes and retrieve the original passwords.

Password Validation

Enforce strong password policies when users register or change their passwords. This includes minimum password length, character requirements (uppercase, lowercase, numbers, special symbols), and avoiding common dictionary words. Stronger passwords translate to more robust hashes, further enhancing security.

Password Re-hashing

Laravel’s Hash::needsRehash() method helps maintain optimal security by checking if the stored hash requires updating with a more secure algorithm as hashing standards evolve. This ensures that even older passwords stored in the database benefit from the latest security advancements.

Regular Security Audits

Conducting regular security audits (as a part of the site maintenance services) is crucial. This helps identify potential vulnerabilities and implement necessary security measures to protect user data.

Remember, the primary goal is to securely manage user credentials, not to retrieve the original passwords.

FAQs on Decrypting Hash Password in Laravel

Why can't I decrypt a hashed password?
Hashing algorithms like Bcrypt and Argon2 transform passwords into unique, unreadable strings. This process is irreversible, meaning there's no mathematical way to retrieve the original password from the generated hash.
What happens if someone gains access to the stored hash values?
Even if an attacker obtains the stored hash values, they cannot decipher them back into the actual passwords. This is a deliberate security measure to safeguard user data even in the event of a security breach.
Are there any alternatives to storing passwords in hashes?
Consider exploring passwordless authentication methods like email magic links or security tokens. These eliminate the need for storing passwords altogether, further enhancing security and user experience.


Hashing is a one-way security measure designed to safeguard user passwords, not a reversible encryption process.

Attempting to crack the hash is futile. But Laravel provides robust tools for secure password management. That includes verification, password resets, and enforcing strong password requirements.

So, if you want to implement the best security practices on your Laravel site, consulting with our Laravel development services would be suitable.
