To calculate file hash checksum values, click right mouse button on any file and choose Properties. Open the hash tab - Hash / CRC. By default, for files up to 20 Mb CRC32, MD5 and SHA-1 checksums will be automatically calculated. Default layout and enabled hashes (checkboxes) can be saved by pressing OK button.

At this point it is possible to check the necessary boxes to calculate other checksum values of file. For calculating MD2, MD4 checksums instead of MD5 or RIPEMD-128, RIPEMD-256, RIPEMD-320 instead of default RIPEMD-160, choose the appropriate hash functions from More menu button.
After necessary checksums are generated, it is possible to copy them to clipboard by clicking Copy button and choosing any or all of previously calculated cryptographic hash value checksum formats.
The following list describes Febooti Hash & CRC property page elements:
| Hash Element | Description |
| Icon | Shows the icon for the file. If it's possible, contents of the file is shown. |
| Name | Displays the name of the file. |
| Location | Shows where the file is located on your computer. |
| 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 highlight, if corresponding matches are found in hash file or clipboard:
|
| MB/s | Shows average hashing speed (KB/s, MB/s or GB/s). Due to disk media latency, for a 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 select another file. For single file, this option is always disabled. |
| Compute button | Calculates selected cryptographic hash values. |
| Copy button | Opens menu that allows to copy any or all calculated checksum to clipboard. |
| More button | Provides more hash options:
|
| Get more modules | Connect to Internet and download newest fileTweak modules. |
| OK | Closes the Hash & CRC, and saves layout and checkboxes state. |
| Cancel | Closes the Hash & CRC, without saving any layout and checkboxes changes. |
