-//! Compute checksums of data.
-//!
-//! De-duplication of backed up data in Obnam relies on cryptographic
-//! checksums. They are implemented in this module. Note that Obnam
-//! does not aim to make these algorithms configurable, so only a very
-//! small number of carefully chosen algorithms are supported here.
