You may end up dragging in a sizeable portion of libcrypto even so. PKCS#7
needs the ASN1 library and the certificate verification library just for
PKCS#7 verification. Those in turn will pull in objects, err, RSA, DSA, EVP,
digests and BIO. The PKCS#7 verification uses BIOs so you wont avoid those
without modifying the way it works quite extensively.

Steve,
Understood. I expected to have to pull in a significant portion
of OpenSSL(libcrypt actually). What I don't understand right now is
why I can't configure out the non-memory BIOs. If the BIOs provide an
abstraction layer for the IO, shouldn't the non-memory BIOs be easily
separable? I am working off limited understanding of the BIOs, so
clarification/correction will be well received.
Thanks again.
