Thanks Mark. Yeah, that may be a problem. Looking at 5.6.2 the old encryptors used SHA1 (5.6.2 release: https://github.com/weidai11/cryptopp/blob/789f81f048c9). Let me get some tests together to confirm it. Once we confirm I'll open an issue for you. Thanks again. Jeff -- You received this message because you are subscribed to "Crypto++ Users".
