Topic: [Simple Query ] Is the wolfSSL library include ECDSA algorithm ?

Hi wolfSSL team,

Is there any module in which we can make use of ECDSA with SHA256 for signature generation, which is required for the project which I'm working presently.

Note: I've gone through ECC algorithm, but specifically I'm asking about ECDSA now.

Thanks in advance.

Hi thippeswamy_dr,

You can use wc_ecc_sign_hash_ex() and wc_ecc_verify_hash_ex() APIs for Elliptic Curve Digital Signature Algo (ECDSA) .

The output parameters r and s would contain the message signature.

You can get more info on the APIs and ECDSA on https://www.wolfssl.com/doxygen/group__ECC.html.

Hope this helps.

Thanks,
Tesfa
