Bcrypt Generator and Verifier
Generate secure Bcrypt hashes from any input text with customizable rounds, or verify whether an existing hash matches a given text.
About this tool
Bcrypt is a secure hashing algorithm widely used for passwords. It includes a unique salt in every hash to help prevent rainbow table attacks. The Rounds setting controls the computational cost: higher values are slower to process, but make brute-force attacks much harder. Even when the same text is used, each generated hash is different.
