+unaesgcm is An AES-256-GCM de-/encryption utility specializing on
+`aesgcm`-scheme URLs as described in the [OMEMO media sharing XMPP
+extension (XEP-0454)](https://xmpp.org/extensions/xep-0454.html) and as
+implemented in modern XMPP clients. The latter meaning, in particular,
+that the initialization vector size is not restricted to 96 bits.
+
+The utility consists of:
+
+* `unaesgcm` command for decrypting local files;
+* `aesgcm-open` command for fetching URLs, decrypting and opening files
+  with associated applications;
+* a desktop entry handling `aesgcm` URLs using a GUI-friendly flavor of
+  the above command;
+* `aesgcm` command for encrypting local files that exists mostly for
+  symmetry.
+
+The utility is intended mainly for development/debugging, as the URLs
+with this scheme are supposed to be invisible to XMPP users, in ideal.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':'.
