Subject: openssl: Don't refer to EVP_des_ecb() if OpenSSL is built without DES support
X-Git-Tag: 5.3.1dr1~9
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f9342fac8f315f43a9c18ff7c623fbddb450928c;p=thirdparty%2Fstrongswan.git

openssl: Don't refer to EVP_des_ecb() if OpenSSL is built without DES support

While DES-ECB is not registered by the plugin in this case (so the
function will never actually be called), the compiler still warns
about the implicitly declared function.
