Re: AES CCM in DTLS v1.2

Thanks, guess I will have to wait for 1.0.2. My aim is still the same though, get rid of the padding required by SHA. As I understand it GCM/GMAC would be a good fit too (?). Will I be able to key it using PSK? Br Fredrik On Tue, Mar 4, 2014 at 10:05 PM, Dr. Stephen Henson wrote: > On Tue, Mar

AES CCM in DTLS v1.2

2014-03-04 Thread Fredrik Jansson
I am currently using DTLS v1.1 but with the introduction of v1.2 in OpenSSL 1.0.1f I was hoping to be able to use AES CCM mode. We use PSK to key DTLS and the resulting algorithm is PSK-AES256-CBC-SHA. Is it possible to stick with PSK and migrate to AES CCM? Best regards, Fredrik
