Function ECDSA_sign

pub unsafe extern "C" fn ECDSA_sign(
    type_: i32,
    dgst: *const u8,
    dgstlen: i32,
    sig: *mut u8,
    siglen: *mut u32,
    eckey: *mut ec_key_st,
) -> i32

Computes ECDSA signature of a given hash value using the supplied private key (note: sig must point to ECDSA_size(eckey) bytes of memory). \param type this parameter is ignored \param dgst pointer to the hash value to sign \param dgstlen length of the hash value \param sig memory for the DER encoded created signature \param siglen pointer to the length of the returned signature \param eckey EC_KEY object containing a private EC key \return 1 on success and 0 otherwise
