Hash Generator

Generate cryptographic hashes from your text using various secure algorithms like SHA-256 and SHA-512.

About this tool

Cryptographic hash functions turn any input into a fixed-length fingerprint — the same input always produces the same hash, but you can't reverse a hash back to the original data. Common uses: verifying file integrity, checking password hashes, and detecting duplicate content.

How to use it

1. Type or paste the text you want to hash.
2. Select an algorithm — SHA-256 or SHA-512.
3. The hash is generated instantly as you type; copy it with one click.

FAQ

Why isn't MD5 or SHA-1 offered?

Both are cryptographically broken and shouldn't be used for anything security-sensitive anymore. This tool only offers algorithms (SHA-256, SHA-512) still considered secure.

Can I hash a file, not just text?

This tool hashes text input only. For file hashing, you'd need a dedicated file-hashing utility.

Will the same input always give the same hash?

Yes — hashing is deterministic. The same exact text will always produce the identical hash with a given algorithm, which is what makes hashes useful for verifying data hasn't changed.
