Function gnunet_sys::GNUNET_CRYPTO_ecdsa_sign_

pub unsafe extern "C" fn GNUNET_CRYPTO_ecdsa_sign_(

@ingroup crypto @brief ECDSA Sign a given block.

The @a purpose data is the beginning of the data of which the signature is to be created. The size field in @a purpose must correctly indicate the number of bytes of the data structure, including its header. If possible, use #GNUNET_CRYPTO_ecdsa_sign() instead of this function (only if @a validate is not fixed-size, you must use this function directly).

@param priv private key to use for the signing @param purpose what to sign (size, purpose) @param[out] sig where to write the signature @return #GNUNET_SYSERR on error, #GNUNET_OK on success
