Default Fixity Algorithm

When ingesting a binary resource, one or more checksums may be provided, see API reference (POST example 4b). The supported algorithms are: SHA-1, SHA-256 and MD5.
By default, the algorithm used by the Fixity service is SHA-1. However, that may be changed to one of the other supported algorithms by configuring the property: fedoraconfig:defaultDigestAlgorithm . See PATCH API reference (PATCH example 2).
