Function pamoja_device_identity_sign 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_device_identity_sign(
    identity: *const PamojaDeviceIdentity,
    payload: *const u8,
    payload_len: usize,
    out_signature: *mut u8,
) -> PamojaStatus

Signs a payload with a device identity.

Returns

PamojaStatus::Ok on success, having written PAMOJA_SIGNATURE_LEN bytes to out_signature.

Safety

identity must be a live handle from pamoja_device_identity_new; payload must point to at least payload_len readable bytes, or be null when payload_len is 0; and out_signature must point to at least PAMOJA_SIGNATURE_LEN writable bytes.
