I need to call HMAC() function in "openssl/hmac" Is there any method to use it in nRF51822?
Thanks in advance.

Hi,
It should be possible to make an embedded version of the hmac function, there several C sources available online. However I do not recommend it as it will have an immense runtime, causing system delays and high power consumption. Instead have a look at this blogpost on application level security using the ECB peripheral.
Best regards,

If one looks around the inter-webs carefully, there are also fine-tuned cortex-mX asm implementations of most of those libraries / functions.
