GPL-compatible libcrypto replacement?

[Thomas Bushnell BSG <tb@becket.net>]

Is there a GPL-compatible libcrypto replacement?  The only libcrypto I
know of is the one bundled with openssl, which AFAICT is under the
same license as openssl itself, which is GPL-incompatible.

We have gnutls as a replacement for openssl itself, but what about
libcrypto?

(Indeed, some things on the web say that gnutls *uses* libcrypto, but
that can't be right.)

It is true that gnutls uses libgcrypt, but libgcrypt doesn't provide
anything like the same symbols as libcrypto.
