If you want to retain the support when OpenSSL makes it available... I think you can pick up RC4 availability via opensslconf.h. If RC4 is disabled, then OpenSSL will define OPENSSL_NO_RC4. For example, here's the define from OpenSSL sources: openssl$ grep -IR NO_RC4 ./* ./apps/rsa.c:#ifndef OPENSSL_NO_RC4 ./apps/rsa.c:#ifndef OPENSSL_NO_RC4 ./apps/speed.c:#ifndef OPENSSL_NO_RC4 ... And here's what an opensslconf.h looks like: $ grep OPENSSL_NO /usr/include/openssl/opensslconf.h | head -n 4 #ifndef OPENSSL_NO_COMP # define OPENSSL_NO_COMP #ifndef OPENSSL_NO_MD2 # define OPENSSL_NO_MD2 Jeff _______________________________________________ nettle-bugs mailing list nettle-bugs@lists.lysator.liu.se http://lists.lysator.liu.se/mailman/listinfo/nettle-bugs
