About Bcrypt
Bcrypt is a password hashing function designed for secure password storage. It incorporates a salt to protect against rainbow table attacks and is adaptive, meaning it can be made slower over time as hardware improves.
The cost factor (salt rounds) determines how computationally expensive the hash operation is. Higher values are more secure but slower.
Hash Format
$2a$10$N9qo8uLOickgx2ZMRZoMy...- $2a$ → Algorithm identifier
- 10$ → Cost factor (2^10 iterations)
- 22 chars → Salt (base64 encoded)
- 31 chars → Hash (base64 encoded)
Salt Rounds Guide
4-7:Fast but less secure
10:Recommended default
12-14:High security applications
15+:Very slow, extreme security
