Hello,

In OpenSSL, is it possible to use the 3DES algorithm in an SSL
connection
so that only 2 keys are used (so that the first and third keys are
they same) ?

If so, could you please tell me how to do it. The need for this is to
use only
112bit key length because of 128bit key export restriction.

Choosing "DES-CBC3-SHA" chooses the 3DES with CBC using 3 keys. I am
not
sure which cipher to choose if we want 3DES with CBC using 2 keys
only.

[There seems to be an init function (des_ede_init_key()) in
~/crypto/evp/e_des3.c which sets the third and the first key to be the
same.
But not clear when it gets invoked.]

Thanks,
Krishna
