You can do this via the lower level API. Something like.. ASN1_OCTET_STRING **pos = CMS_get0_content(cms); Then the content is ASN1_STRING_length(*pos) bytes using the buffer ASN1_STRING_data(*pos). Note that those are internal pointers which should be treated as read only. Steve. -- Dr Stephen N. Henson. OpenSSL project core developer.
