About Hash Generator

This free online hash generator helps you create cryptographic hash values from text using various algorithms. Hash functions are commonly used in digital signatures, message authentication codes, and other security applications. Note that MD5 and SHA-1 are considered cryptographically broken and should not be used for security-sensitive applications.

Frequently Asked Questions

A hash function is a mathematical algorithm that takes an input (or 'message') and returns a fixed-size string of bytes. The output is typically a 'digest' that is unique to each unique input. Even a small change in the input will produce a significantly different output.

For security-sensitive applications, use SHA-256 or SHA-512 as they are currently considered secure. MD5 and SHA-1 are cryptographically broken and vulnerable to collision attacks, so they should only be used for non-security purposes like checksums or data integrity verification in non-adversarial environments.

Yes, your data is completely safe. All hash generation happens locally in your browser - your input is never sent to our servers. We don't store or track any of the data you hash.

While you can generate password hashes with this tool, it's not recommended for secure password storage. For password hashing, you should use specialized algorithms like bcrypt, Argon2, or PBKDF2 that are specifically designed to be slow and resistant to brute-force attacks.
