At a mere 57k, his checksum tool is about as small as a useful, functioning utility can be in this age of bloatware, and even more so considering that it's certified to work in Windows Vista and 7. MD5 & SHA-1 Checksum Utility is free to download and use, though Ray accepts donations from satisfied users.

A Paste function automatically enters the generated hash for verification at the click of a button. Copy the following VBScript code to Notepad. certutil.exe -hashfile filename SHA256 If you want to implement Certutil.exe in your right-click menu, here is a VBScript that exactly does it. To generate or verify a hash, you simply browse to the file of choice, select either MD5 or SHA-1, and click either Copy to generate the hash or Verify to check its integrity. The following command-line syntax is to be used to calculate the SHA256 checksum of a file using Certutil.exe from a Command Prompt window. The program has a basic, utterly functional interface that should pose no trouble for anyone with the knowledge and skill to actually need it. There are two basic types, those that calculate checksum values and those that also validate them by checking them against a list of values for the protected data, which is the only way it can be done. Checksum utilities are used to verify the integrity of generated hashes. If the hashes do not match there is corruption in the file, and it should be downloaded again ideally using a download manager rather than through the browser. Two of the most common cryptographic hash functions are the Secure Hash Algorithm (SHA) and Message Digest Algorithm-5 (MD5). Its also very trivial for the user to use this command to verify the integrity of all the files, recursively.
Cryptographic hash functions are commonly used to guard against malicious changes to protected data in a wide variety of software, Internet, and security applications, including digital signatures and other forms of authentication. Its trivial to use this command to generate this file with the recursive SHA256 checksums of all the files in the current directory and subdirectories. Raymond Lin's MD5 & SHA-1 Checksum Utility is a standalone freeware tool that generates and verifies cryptographic hashes in MD5 and SHA-1.
