+ * BIO instead of a uri, along with a scheme to use when reading.
+ * The given UI method will be used any time the loader needs extra input,
+ * for example when a password or pin is needed, and will be passed the
+ * same user data every time it's needed in this context.

+ * through.
+ *
+ * Note that this function is considered unsafe, all depending on what the
