Hi all, I'm very new to M2Crypto, and I'd like to obtain a detached digital signature (pkcs#7 format) for a file , let's say a png file for example: sample.png -> sample.png + sample.png.pkcs7 Is that possible via M2Crypto ? Any suggestion / sample code ? Best Regards, Jean ---- Introducing Spymac MailPro: http://www.spymac.com/mailpro/
