About Hash Generator
Generate cryptographic hashes from any text input. Supports MD5, SHA-1, SHA-256, and SHA-512. Hashing is a one-way operation — useful for verifying data integrity, storing password fingerprints, and generating checksums. Computed entirely in your browser using the Web Crypto API.
FAQ
- Which hash algorithm should I use?
- For general integrity checks, SHA-256 is the standard choice. MD5 and SHA-1 are considered weak and should not be used for security-critical applications.
- Can you reverse a hash back to the original text?
- No. Hash functions are one-way by design. You can't recover the input from the output — that's what makes them useful for password storage and data verification.
- Is my data sent to a server for hashing?
- No. Hashes are computed locally in your browser using the Web Crypto API. Your input never leaves your device.
