Thanks, Dr. Stephen:
I have to confess that I have never used OpenSSL library. Could you please provide some sample code (or outline the steps and the related OpenSSL functions)?
Thanks a lot for your help!
Louis

That algorithm is already implemented by OpenSSL in the EVP_PBE_CipherInit() functions, they aren't documented yet though.
In outline you call these in a similar fashion to EVP_CipherInit(), the extra paramaters are in the "type" parameter which can be set with PKCS5_pbe_set().
