SHA-512 File Checksum

Calculate a SHA-512 fingerprint of any local file in your browser.

How to use

1. Select a file and calculate its SHA-512 hash locally.
2. Compare all 128 hexadecimal digits against an independently verified reference.

About these formats

SHA-512 generates a 512-bit cryptographic digest (128 hexadecimal digits); it is not encryption or a digital signature.

Browser limitations

The Web Crypto implementation buffers input in memory; large files may be limited by available device RAM.

Frequently asked questions

Is SHA-512 stronger than MD5?

Yes. Unlike MD5, SHA-512 is a modern cryptographic hash suitable for integrity verification.

Is the file uploaded?

No. Hashing uses the Web Crypto API in your browser.
