Overview

Hasher is a file checksum and verification utility. It computes cryptographic hasheshash values for any number of files and letstext, so you verifycan confirm that files have not been corrupted or tampered with during transfer or storage.

Hashing files is as simple as dropping them into the window. Multiple algorithms are computed in a single pass, with results displayed alongside file metadata. The same capability extends to arbitrary text strings, useful for verifying snippets or checking algorithm output.

Comparison tools make integrity checks straightforward. Verify a file against a known hash string, or compare two files directly against each other. The session log records all hashed files and their results, exportable to standard checksum formats for easy distribution alongside your files.

A wide range of algorithms is supported: CRC32, MD2, MD4, MD5, SHA1, SHA256, SHA512, RipeMD128, RipeMD160, and ED2K. Multiple hash types can be computed for the same file in a single pass, and results can be exported to standard verification file formats: SFV, MD5SUM, and SHA1SUM, making it straightforward to share checksums alongside distributed files.

Built-in comparison shortcuts speed up integrity checks. Hold Shift to compare a file against the next added file, or Ctrl to compare the next two files.
