Seeking help for crypto libraries for RISC V.

[sathish kumar ganapathy]

Hello All,

I am Sathish, pursuing a master's degree. I am currently doing my master's thesis. I am working with RISC V core, and I have to integrate the crypto libraries for RISC V and use it in my application.

I am new to RISC V and crypto. Can Someone please help me to find the cryptographic libraries for RISC V bare metal programming? As I want to integrate it and use those API's in my user application.

Note: The RISC V core with which I am working doesn't have crypto extension support. So searching for a crypto library that supports using its general instruction set.

Thanks in Advance.
Best Regards,
Sathish

What language(s)?

What exactly do you mean by "crypto" libraries?

What specific crypto capabilities do you need support for?

Any library coded mainly or completely in a high-level language should be capable of being compiled for any RISC-V arch/abi. Most likely, it will only depend on crypto extensions if it explicitly uses the relevant instructions via assembly language code.

Thanks for the reply.

What language(s)? 

  - I looking for a library written in c

What exactly do you mean by "crypto" libraries?

 - I am looking for an AES and HMAC library.

What specific crypto capabilities do you need support for?

- I like to encrypt the data using AES and authenticate with HMAC.

- Okay understood. Thanks for the explanation.

So, I would start by searching for open-source implementations of these algorithms and seeing what's involved in compiling them for RISC-V and, if necessary, wrapping them in whatever sort of APIs you need for your purposes.

Maybe this would be worth looking at?

* https://github.com/kokke?tab=repositories

It has repos for what look like small/efficient/simple implementations of AES and HMAC...

* https://github.com/kokke/tiny-AES-c

Thank you for providing me with this information. I will look into it.
