Dan;

It is most likely from a dev package.  I have an aes.h on my system
that comes from libssl-dev.  I have no aes1.h.

$ dpkg-query -S /usr/include/openssl/aes.h
libssl-dev: /usr/include/openssl/aes.h

Is the file an actual header file?  If so it should start with
something like the following, with a lot of defines and includes in
the actual code.

/* crypto/aes/aes.h -*- mode:C; c-file-style: "eay" -*- */
/* ====================================================================
 * Copyright (c) 1998-2002 The OpenSSL Project.  All rights reserved.
...
#ifndef HEADER_AES_H
#define HEADER_AES_H

#include <openssl/opensslconf.h>

#ifdef OPENSSL_NO_AES
#error AES is disabled.
#endif

What version of Ubuntu/openssl are you currently running?  The .h
files would only be used at compile time, if you are worried about it
there is no reason you could not either remove the file or the -dev
package it belongs to (unless you want to compile something with ssl
support).
