Open Source Command Line SHA1/MD5 Checksum Generator

Checksum Calculator is an easy-to-use checksum utility for Windows which allows to compute the SHA1/MD5 cryptographic checksum for a specified file or text string in the command prompt mode.

Free and Open Source Command Line SHA1/MD5 Generator


  • Simple and lightweight.
  • Supported algorithms include: MD5, SHA-1, SHA-256, SHA-384, SHA-512.
  • Supported text encoding formats include: ASCII, UTF8, UTF7, UTF16, UTF32.
  • Allows to export calculated signature to external file.

It’s a good idea to rename the executable file( “checksum.exe” ) to something easy to remember and type such as “MD5.exe” and copy it to your Windows system folder( for example, C:\WINDOWS ), then you can use it as if it’s a system’s native command.

Experienced Windows users can even write a batch script( BAT file ) to calculate the MD5/SHA1 value of large batches of files at once by invoking this command line utility.

Checksum Calculator is developed by atanamir, it works on Windows 7 and Windows XP.
