Hash text or a file locally and view the digest in four formats
Up to 4 MiB of UTF-8 text. Spaces, line breaks and BOM are preserved; empty text also has a hash
Hash text or a file locally and view the digest in four formats
A hash is not encryption and does not authenticate a file’s sender. Do not store passwords using plain SHA. Decimal uses an unsigned big-endian integer; binary keeps leading zeroes
File reading can be stopped. Once browser hashing starts it cannot be interrupted; cancellation discards the result and prevents another run until it finishes
Enter text or choose a file, calculate the hash, then choose a format and copy. Text imports require valid UTF-8; File mode preserves every original byte. All computation is local
