Fix compiler warnings. Reported by GCC with flags:

Browse Source 
-Wall -Wall -Werror=format-security -Wp,-U_FORTIFY_SOURCE,-D_FORTIFY_SOURCE=3 -Wp,-D_GLIBCXX_ASSERTIONS

Note, e.g. sprintf(digest, "%s%02x", digest, ...) is undefined behaviour because
the destination and source variables overlap, and GCC warnings for this.
