tinc/src/digest.h
Guus Sliepen cfe9285adf Allow tinc to be compiled without OpenSSL.
The option "--disable-legacy-protocol" was added to the configure
script. The new protocol does not depend on any external crypto
libraries, so when the option is used tinc is no longer linked to
OpenSSL's libcrypto.
