Hash Generator & Verifier
Generate MD5, SHA-1, SHA-256, SHA-512, and bcrypt hashes. Verify strings against known hashes. Use the tabs below to generate or verify hashes.
Input
Enter the text you want to hash.
Bcrypt Options
Configure the cost factor (rounds) for bcrypt hashing.
Performance Note
Higher bcrypt rounds increase security but are significantly slower, especially in the browser. 10-12 is typical.
Generated Hashes
Results for various algorithms.
MD5 is cryptographically broken and should not be used for security purposes (like passwords).
SHA-1 is considered weak and should be avoided for security applications.
