Frequently asked questions
How long is a SHA-256 digest?
SHA-256 produces 256 bits, shown as 64 hexadecimal characters. It belongs to the SHA-2 family and is widely used for package and download checksums.
Does matching SHA-256 prove who published a file?
A match shows that your bytes have the expected digest. SHA-256 is designed for collision resistance, but authenticity also depends on obtaining the expected digest from a trusted source.
Can I paste a shasum output line?
Yes. Paste the hexadecimal digest with its filename. Comparison uses the first whitespace-delimited token and ignores letter case. This Tool reads files whole, up to 100 MB.
