Description: bcrypt is a widely-used password hashing algorithm that incorporates a salt to protect against rainbow table attacks and an adaptive cost factor to prevent brute force attacks.
Cost Factor: The cost factor can be adjusted to increase the computational effort required to hash a password, making it more resistant to brute force attacks.
Implementation: bcrypt is implemented using the bcrypt
library, which is a well-maintained and widely-accepted library for password hashing.
Description: Argon2 is an advanced password hashing algorithm that won the Password Hashing Competition in 2015. It is designed to be resistant to GPU cracking attacks and offers configurable memory and time costs.
Memory and Time Costs: Argon2 allows the customization of memory and time costs to balance security and performance.
Implementation: Argon2 is implemented using the argon2
library, which is recommended for new applications due to its enhanced security features.
Generation: A unique salt is generated for each password using a cryptographically secure random number generator.
Length: The salt length is typically 16 bytes, providing sufficient randomness to protect against pre-computed attacks.
Storage: Salts are stored alongside the hashed passwords in the database.
