QuickHash

QuickHash is a utility to quickly display the MD5, SHA1, SHA256, SHA384, SHA512, (and SHA3 in v2.x) hashes of any selected file, and optionally compare the hashes with any hash string.  Useful for verifying the file integrity and authenticity of your file downloads, ensuring the contents have not changed during transmission or from malicious activity.

Wikipedia articles (WARNING:  External Links follow) for the Hash Function and File Verification may help shed some light on the nature of these terms and usage.

QuickHash comes in two versions:   (both are free for personal and commercial usage.)

• v1.x – does not require the .NET Framework (suitable for usage in older Windows operating systems such as Windows XP – Windows 7 that may not have the .NET Framework installed, and also WinPE environments) but may hang or report invalid data on files approaching 2GB in size.

• v2.x – adds the newest SHA3 hash support in addition to supporting files greater than 2GB in size, but requires the .NET 4 Client Profile (this is already installed by default on Windows versions 8.0 and newer.)

 

Current Version:  v2.0.1.5 (Released Dec 14th 2016) adds a number of new features!
(QuickHash v2.x requires the .Net 4 Client Profile to be installed)

• Ability to select and hash multiple files within a single tabbed interface
• Ability to enable/disable hash calculations per hash type (click on text box area to calculate/recalculate on demand)
• Ability to submit malicious files to Foolish IT for review (allowing hash definition creation for use within our other products such as CryptoPrevent Malware Prevention, dFunk (d7II PC Technician Software), KillEmAll v5, etc.)
• Display the time in seconds it took to calculate the hash type
• Built in updating feature
• Added optional debug logging information
• Using a config file to save settings for portability

Current Version:  v1.1 (Released Jan 25th 2016 per user request) adds SHA384 and SHA512 hash support!
(QuickHash v1.x DOES NOT require any components of the .Net Framework, but will hang or display incorrect data on large files starting at 2GB.)

QuickHash is a utility to quickly display the MD5, SHA1, SHA256, SHA384, and SHA512 hashes of any selected file, and optionally compare the hashes with any hash string.  Useful for verifying file downloads (less than 2GB).

• Run QuickHash and browse for a file, hashes will automatically be displayed.
• Drag and Drop a file directly onto QuickHash.exe to automatically hash that file without having to use the Browse dialog.
• Use the Compare Hash button and paste in a file hash string (MD5, SHA1, SHA256, SHA384, or SHA512) to quickly determine if your hash string is identical to any of the selected file’s hashes.

 

(Does not require .NET runtime!)
