It does. This would come under the "unless you absolutely need it" exception.
note that symmetric encryption is also really hard. it wasn't until 2010 or so that GCM mode came around and provided a system that is somewhat easy to implement without accidentally breaking everything.
GCM is not without it's own pitfalls though, however.
