Overview

Hasher is a file checksum and verification utility. It computes cryptographic hashes for any number of files and lets you verify that files have not been corrupted or tampered with during transfer or storage.

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.
