About Lesson
bcrypt encoder is a cryptographic hashing function specifically designed for securely storing passwords. It takes a password as input and generates a hash string, which is a fixed-length representation of the original password. The key feature of bcrypt is its ability to adjust its computational cost, making it slower to compute hashes. This deliberate slowness makes it resistant to brute-force attacks, where an attacker tries many possible passwords in a short amount of time. Additionally, bcrypt automatically handles the generation of a random salt for each password, further enhancing security. Overall, bcrypt encoder is widely used in applications to protect user passwords against unauthorized access.
- .encode(): This method is used to encode or hash a plaintext password. It takes the plaintext password as input and generates a hashed representation of it using the bcrypt algorithm. The resulting hash is then typically stored securely in a database.
- .verify(): This method is used to verify whether a plaintext password matches a previously hashed password stored in the database. It takes two parameters: the plaintext password and the hashed password retrieved from the database. It then compares the hashed representation of the plaintext password with the stored hashed password. If they match, the method returns true, indicating that the passwords are the same. Otherwise, it returns false, indicating that the passwords are different. This method is crucial for verifying user passwords during the login process, for example.
