How to Generate a Hash (SHA-256, MD5, and More)
Published September 12, 2026 · 3 min read
Hashing is used to verify file integrity, generate checksums, or create a fixed-length fingerprint of some data. This tool computes several common hash algorithms over text you type or a file you select, without uploading anything.
Try Hash GeneratorSteps
- 1
Open the Hash Generator tool
Go to the hash generator.
- 2
Enter text, or select one or more files
Type text directly, or choose files to hash their exact contents.
- 3
Choose an algorithm
Pick SHA-256, SHA-1, SHA-384, SHA-512, MD5, or CRC32.
- 4
Copy the hash
Use it to verify integrity or as a checksum.
Frequently asked questions
SHA-256 is the standard modern choice for most purposes; MD5 and SHA-1 are still common for legacy compatibility or quick checksums, though neither is considered secure for cryptographic purposes anymore.
Yes — select several files and each one's hash is listed separately alongside its filename.
No — the file's bytes are read directly into your browser's memory and hashed there; nothing is uploaded to compute the result.
Because hashing runs locally, you can verify a sensitive file's integrity or checksum without ever sending the file itself anywhere.
