SHA256 Hash

Git identifies every commit and every file internally by its own SHA-1 hash of that content, which is why a hash occasionally needs computing or checking outside of git itself, confirming a blob's hash matches what git reports, or working with a legacy system or an API that specifically expects SHA-1 rather than MD5 or SHA-256. This tool generates a SHA-1 hash from pasted text or an uploaded file, with the result ready to copy immediately rather than needing to be selected out of a longer output.

Useful for confirming a file's SHA-1 hash matches what a git object reports internally, generating a hash for a legacy system that specifically requires SHA-1 over a newer algorithm, or quickly verifying two pieces of text are identical by comparing their hash output.

Quick answers for SHA-1 Hash Generator

Do I need to click a button, or does it hash as I type?
You click Generate Hash after typing, it does not hash on every keystroke, the result then appears below with its own Copy button.
Can I switch algorithms without retyping my text?
Yes, MD5, SHA-1, and SHA-256 are separate buttons above the input, picking a different one and clicking Generate Hash re-hashes the same text you already typed.
Does it accept file uploads?
No, there's only a text box, to hash a file's contents you'd need to paste that content in as text rather than upload the file directly.
