Unless you want to process a huge amount of data the normal DER functions will suffice. Check the documentation that came with your version of OpenSSL for details. For a detached signature you can output it using d2i_PKCS7_bio(). See also: http://www.openssl.org/support/faq.html#PROG4 Steve. -- Dr Stephen N. Henson.
