Hello!

Sorry to have given you false hopes. The issue that all the data
has to
be in working memory to be encrypted is indeed starting to become
a real
annoyance in some practical circumstances. So perhaps if Stephen
Henson
should develop the feature further one day we can volunteer as
testers? ;-)
'tis done.
I found a quiet period to look into it and test it a little. Check
out the new
-stream option in the smime utility for OpenSSL 0.9.9.
Support in the API is quite simple too, just include the
PKCS7_STREAM flag in
the calls to PKCS7_{sign,encrypt} and SMIME_write_PKCS7() see the
docs for more
info or the new examples in demos/smime. Chaining isn't possible
using that
method however (e.g. sign & encrypt) that would need major API
changes.
Any problems let me know. Money back if not completely satisfied :-)
After having played a little bit with the openSSL sources (without
success) I wonder if it's technically possible to add the new
streaming support for SMIME verification and decryption too. Is there
anybody out there who can help me out?
Greetings,
Harald
