application...

Any help is highly appreciated...

PKCS7_DataInit() and PKCS7_DataFinal() are low level PKCS7 routines used
for signing and encrypting data in PKCS#7 routines for S/MIME. Unless
you have a good reason for using them the higher level routines
PKCS7_sign() and PKCS7_encrypt() should be used instead.
