Problems in Using nrf crypto hash function

[peurpdapeurp]

Hello all. I have been having issues using the hash functionality of the nrf crypto library.

Above is the screenshot of the output I am getting for the code shown below:

What I am confused about is two things: it seems that the error code that the function returns (30466) is not defined anywhere, so I am lost on what is actually going wrong.

In addition, it is even more bizarre to me because I have another piece of code based on the nrf crypto library somewhere else in my library that actually does work, and is almost identical to the code that is causing problems:

Both of these functions can compile, but one of them works and the other returns an error that is not defined, and I am not sure what the difference is.

I have actually been having rather a lot of trouble in getting the nrf crypto libraries to work when I move them to different files like this, and it makes me think that maybe I am doing something wrong; I am calling nrf_crypto_init(), but is there something else that I have to do that I need to do in order to get the nrf crypto library to work when it is not in the main.c file?

Thank you very much for any advice or help.

Just as an update, it seems that even when I include the function that I thought worked (sign_on_basic_nrf_crypto_gen_sha256_hash) and try to call it within the file where nrf_crypto_hash_calculate was failing, the function also fails there, so I guess where nrf_crypto_hash_calculate is called from has an effect on whether or not it will succeed or fail?

Hi the error you are getting is 34066 (0x8512) (from the screenshot, not 30466 as you write in the post)

You can find the error code here: NRF_ERROR_CRYPTO_INPUT_LOCATION

"Input data not in RAM". So most likely you are passing a pointer to a locally defined variable. You need to make the variable static, or use memset.

Hi,
This error means that data you are using is located in Flash hence it cannot be proceed. Just copy your data to RAM (global or static variable) and next process it.
