Technical Insights into Bcrypt
Bcrypt is a password-hashing function designed to be computationally intensive, making brute-force
attacks slower and more difficult.
- Salt Rounds: Determines how many iterations of the hashing algorithm are
applied. Higher values are slower but more secure.
- Automatic Salting: Bcrypt generates a random salt internally for each hash.
- Security Benefit: Even if two users have the same password, their hashes will
differ due to unique salts.
- Verification: To check a password, bcrypt re-applies the same process with the
stored salt.
Choosing the right salt rounds is a balance between performance and security.
