File Checksum

Filemanager offers the posibility to create and to verify checksum file hashes using its interface allowing multiple file hashing algorithms (configurable) to be used.

Configuration

By default only 2 algorithms are enabled in the plugin configuration:

• CRC32 aka SFV
• SHA256

The support for file hashing is offered by 7zip's hashing functionality. You can see the supported algorithms of your 7zip by using the i flag, under the Hashers section:
