ARGON2ID – A Strong Password Hashing Algorithm
About Argon2ID
Argon2ID is a password hashing algorithm designed to be more secure than traditional methods such as SHA-256. It was developed by John Heller for use in password hash functions.
- It uses a salt value to make the hash unique per-password.
- It includes a large amount of work factor to increase time complexity.
- It is resistant to brute-force attacks through key derivation functions.
Syntax for Argon2ID
password_hash = argon2id(args=(16, 16), m=16, iterations=10000)
print(password_hash)
The above example demonstrates how to use Argon2ID with the required parameters: iterations, m, and the salt value.
Example Usage
Here's an example of using Argon2ID in Python:
import argon2
salt = b'abcdefghijklmnop'
work_factor = 16
iterations = 10000
hash = argon2.argon2id(salt=salt, work_factor=work_factor, iterations=iterations)
print(hash)
Why Argon2ID is More Secure
Argon2ID provides better security compared to older algorithms due to its high computational cost. It prevents attackers from quickly cracking passwords through brute force.
Implementation Details
Argon2ID works by taking a password and a salt, then performing a series of computations on them before outputting the final hash. The number of iterations determines how much computation is required, making it harder for attackers to reverse-engineer the original password.
Usage in PHP
If you're using PHP, here's a simple way to use Argon2ID:
$hash = argon2id($password, $salt);
echo $hash;
Conclusion
In conclusion, Argon2ID is a strong and widely-used cryptographic hash function that is recommended for use in password hashing scenarios. Its design makes it highly resistant to attacks and ensures secure storage of sensitive information.
