I would like use ECDSA for signatures rather than RSA in a native app.

Is there a simple way to use the underlying OpenSSL libraries from native code?

Or will I have to build OpenSSL for tizen separately and link it in?

Thanks!

Edit:

On the same topic, does anyone know if the RSASignature class implements PKCS#1 v1.5 (RSA) or v2.1 (RSA-PSS)?
