Attention is currently required from: plaisthos.
Hello plaisthos,
I'd like you to do a code review.
Please visit
http://gerrit.openvpn.net/c/openvpn/+/1133?usp=email
to review the following change.
Change subject: Handle return type of EVP_MD_size
......................................................................
Handle return type of EVP_MD_size
Return type is int, but we often use it in contexts
where we expect size_t. So just cast it. Nothing else
to do really.
