Hash & CRC is a freeware cryptographic hash value calculator that allows computing MD5, SHA-1, CRC32 and other popular hash checksums of files.

Overview

To calculate file hash checksum values, click the right mouse button on any file in any window, and choose Properties option. Activate the hash tab. That's it!

Access Windows file Properties

Checksums will be automatically calculated for files up to 20MB CRC32, MD5 and SHA-1 by default. The default layout and active hashes can be saved by clicking the OK button.

After necessary checksums are generated, it is possible to copy them to the clipboard by clicking the Copy button.

Item Description
Icon Shows the icon for the selected file.
Name Displays the name of the file.
Location Shows where the file is located.
Checkboxes Specifies the cryptographic hash values to be calculated. By default, CRC32 and MD5 and SHA-1 hashes are enabled. Click on Show more button to show all other hashes.
Hash values Displays computed hash value for each selected hash function. Additionally, hash value is highlighted, if corresponding matches are found in hash file or clipboard:
  •   Found match in file: hash file;
  •   Found match in Clipboard (updated in real-time);
  •   Found match both in hash file and Clipboard;
  •   Regular hash.
MB/s Shows average hashing speed (KB/s, MB/s or GB/s). Due to disk media latency, for very small files (below a few megabytes), speed may be significantly lower than it would be for larger files. View hash benchmark.
View file Displays the name of the file and allows you to select another file. For a single file, this option is always disabled.
Compute Calculates selected cryptographic hash values.
Copy It opens a menu that allows copying any or all calculated checksum to the clipboard.
More Provides more hash options:
  • Allows to choose additional hash functions (MD5, MD4, MD2) and (RIPEMD-128, RIPEMD-160, RIPEMD-256, RIPEMD-320) for hash calculations.
  • Show more hashes or Show less hashes—change the default layout.
  • Show in UPPERCASE or Show in lowercase—change case of the final hash.
  • Online help—opens this very help.
  • Test vectors—opens hash test vectors grid.
  • Release notes—opens Hash & CRC release notes.
OK Closes the Hash & CRC, and saves layout and options.
Cancel Closes, without saving any layout and option.
