Unsigned attributes to PKCS#7

2004-09-01 Thread Antonio Ruiz Martínez 
Hello!
   I would like to add a TimeStamping to a signed PKCS#7 and I have got 
some questions:
- Is it the TimeStamping structure in asn.1 defined in openssl (or 
planned)?
- Is there some attribute defined in Openssl to add the time stamping 
structure to a PKCS#7 as an unsigned attribute (is the 
PKCS7_add_attribute the proper function?) ?

Could you help me, please?
Thanks in advance,
Regards,
Antonio.

rfc 3161 timestamps are currently not implemented in OpenSSL, but
you can use the Openssl patch from www.opentsa.org or use the libs
from https://www.openevidence.org
