A patch to gcrypt was proposed on the mailing list to add SM3, a hash
function sponsored by a Chinese government body. The function contains
unjustified changes and picked constants.

Is it possible the hash function is insecure? I am of the opinion that
it is, but despite my concerns the patch was merged with gcrypt.
