PKCS#7 Signed-data problem

[Cathy Yeh]

Hi all,   I'm working on packing PKCS#7 Signed-data type with latest OpenSSL snap-shot. However, if we did not call "PKCS7_set_detached(p7s,1)" function to set it as detached type, exception would occure after calling BIO_write(..) to write data to PKCS7 structure. It seems the function ( PKCS7_set_detached(..) ) is required to generate a Signed package. But apparently the followed verification would be failed since no detached file was supplied. Did anyone meet the same situation? How did you solve this problem? Please kindly give your advise or comment. Thanks!
