commit 76fac8b15d15e9371e71007b9f7d28d17ec4234e
Author: Michał Trojnara <Michal.Trojnara at stunnel.org>
Date:   Thu Mar 10 09:42:24 2016 +0100

    Restored support for ANSI X9.31 RSA
    
    OpenSSL uses this padding in crypto/rsa/rsa_pmeth.c.
    It is also trivial to implement, as it does not have a parameter.
