From 4b559b4ddffc0b7f688019bcb80658f05e063af7 Mon Sep 17 00:00:00 2001 From: "rvargas@google.com" Date: Thu, 14 Apr 2011 17:37:14 +0000 Subject: Move crypto files out of base, to a top level directory. src/crypto is now an independent project that contains our cryptographic primitives (except md5 and sha1). This removes the base dependency from nss, openssl and sqlite.
