Re: DH_compute_key query

Steve, It is word aligned. I tried different ways to prepend the value in DH-d but it is not working. When I dump the memory it shows leading zeros but when I print the same DH-d using BN_print_fp it does not show zeros which is expected but leading zeros are not increasing the num_bytes

Re: DH_compute_key query

Steve, I am also facing a similar issue. In my case the key generated by DH_compute_key need to be used by hash function for authentication purpose. Even after prepending the key with zeros, hash'd value is not same as the other end. Is there any built-in or openSSL function that will prepend

Re: DH_compute_key query

Sindya, Looking at the hexdump issue earlier in the thread, I have a question for you. Is your memory buffer block or word aligned? Some mismatch here may cause some block computation issues. - Steve Steve, I am also facing a similar issue. In my case the key generated by DH_compute_key

Thanks Steve a ton. I think I was missing some basic design understanding. -Prashant On Fri, Jul 22, 2011 at 5:08 PM, Dr. Stephen Henson st...@openssl.orgwrote: On Thu, Jul 21, 2011, Prashant Batra wrote: Hello, I am using DH exchange in ikev2 for generating secret key b/w 2 parties.
