Hash Generator
DeveloperNewInstantly compute cryptographic hash digests for any text input using multiple algorithms.
Frequently asked questions
How do I generate a SHA-256 hash of a string online?
Type your text into the input field and the MD5, SHA-1, SHA-256, and SHA-512 digests are all computed and displayed at once, so you can copy whichever algorithm you need without re-entering the text.
Is MD5 still safe to use for passwords?
No. MD5 and SHA-1 are considered broken for security purposes because collisions can be engineered, they are only included here for checksums and compatibility with legacy systems. Use SHA-256 or SHA-512 for anything security-related.
Can this tool hash files, not just text?
This tool hashes text input you paste or type. If you need a checksum for a file, you would need to open it as text first since the hash functions operate on the string content, not binary file uploads.
Why does the same word produce a different hash each time?
It should not. Cryptographic hash functions like SHA-256 are deterministic, so identical input always produces an identical output. If you see different results, check for trailing spaces or line breaks that changed the actual input text.
