OpenSSL to request and verify time stamps. OpenSSL is an open-source tool that is popular with Internet software developers. It includes a command line tool that can be used to retrieve and verify DigiStamp timestamps. Jul 23, 2013 Paul, thank you for your answer. It looks like that p7m is encoded in base64, maybe SMiMEreadPKCS7 method does not support p7m containers? Also I tried use the following function instead of SMIMEreadpKCS7: p7=d2iPKCS7bio(in,NULL); It works but after the p7 is decrypted output contains a lot of system data – XFactor Jul 23 '13 at 8:25.
