A simple module to allow repository managers to enable the creation of a checksum for objects. If enabled, the following checksum algorithms are available: MD5, SHA-1, SHA-256, SHA-384, SHA-512.
This will checksum all datastreams.
Note: There is a difference between a security application of SHA and data integrity application of SHA. Islandora's application is for the latter, for data integrity. For Islandora's purposes, any of the checksum algorithms can be used.
Release Notes and Downloads
Unzip this module into your site's modules directory as you would any other contrib module. See this for further information.
Enable and set checksum type in Administration » Islandora » Islandora Utility Modules » Checksum (admin/islandora/tools/checksum). To retroactively enable checksums on existing objects, enable and set checksum type if you have not already done so, and choose a collection and click on the 'Enable' button.
