What is this tool?
Hash Generator computes cryptographic hash values of input text using multiple algorithms including MD5, SHA-1, SHA-256, SHA-512, and others. Hash functions produce fixed-length outputs from variable-length inputs and are one-way—impossible to reverse. Used for password storage, file integrity verification, digital signatures, and data deduplication.

Frequently Asked Questions
Should I use MD5 or SHA-256?
MD5 is considered cryptographically broken and should not be used for security. SHA-1 is also deprecated. Use SHA-256 or SHA-512 for security applications. MD5 is still acceptable for non-security checksums and data deduplication.
Can hashes be reversed?
No. Hash functions are one-way by design. Given a hash, you cannot determine the original input. However, short or common inputs can sometimes be found in pre-computed rainbow tables. This is why passwords should be salted before hashing.
Is this safe to use with real passwords?
All operations happen locally in your browser. However avoid pasting passwords into any web tool if possible.
