+Checksums in Resolver were historically used during transport, 
+to ensure Artifact integrity. In addition, latest Resolver may 
+use checksums in various other ways too, for example to ensure 
+Artifact integrity during resolution. 
+
+The bare essence of all checksum uses in Resolver is 
+"integrity validation": Resolver calculates by various
+means the "calculated" checksum (for given payload), 
+then obtains somehow the "expected" checksum (for same payload)
+and compares the two.
+
+This page covers all the "expected" checksum varieties.

+
+Historically, the "obtain expected checksum" was implemented as simple HTTP GET 
+request against Artifact checksum URL (Artifact URL appended by ".sha1"). This logic
