Issues to be addressed for src/lib/crypto: -*- text -*-

Many files here and in subdirectories pollute the namespace.

However, some applications wanting to directly use some of those

routines will expect those names to be available.

Workaround: Shared library export lists?  Define and export internal

names, and provide wrapper library code or weak functions under the

polluting names?

Some routines assume "int" is big enough to describe all buffers that

may be supplied.
