Overview

This project provides two programs for file integrity verification.

• fchksum
  
  • Report checksums for files.
  • Create checksum lists (containing checksum and file name) for a list of files.
  • Test whether file checksums match the checksums in a checksum list.
• fchksize
  
  • Report sizes for files.
  • Create file size lists (containing file size and file name) for a list of files.
  • Test whether file sizes match the sizes in a file size list.

Checksums are created by generating a binary message digest which is encoded either ASCII-Hex, ASCII-85 or reverse ASCII-85.

This project does not implement message digest algorithms itself, it uses the MD5, RIPEMD-160, SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 implementations provided by the OpenSSL library, see http://www.openssl.org.

The software is licensed to you under BSD-style license terms, see FAQ for details.

Windows binaries are available in the dklibs-win32 package in the ``Downloads'' area of the dklibs SourceForge project.
