Issue and verify vouchers

example

```rust fn main() { let start = std::time::Instant::now(); let result = calldynamic().expect("运行出错"); let usetime = start.elapsed(); println!("success :{} 总用时：{}毫秒", result, usetime.asmillis()); }

fn calldynamic() -> Result> { unsafe { let start = std::time::Instant::now(); let lib = libloading::Library::new("./src/libwdpassport.dylib")?; let signfunc: libloading::Symbol< unsafe extern "C" fn( data: *const cchar, timestamp: clonglong, sign: *const cchar, ) -> c_int,

= lib.get(b"sign")?; let verifyfunc: libloading::Symbol< unsafe extern "C" fn( data: *const cchar, sign: *const cchar, timestamp: clonglong, ) -> cint, = lib.get(b"verify")?; let usetime = start.elapsed(); println!("启动用时：{}微秒", usetime.asmicros());

    let start = std::time::Instant::now();
    let data = CString::from_vec_unchecked(Vec::from("hello world"));
    let sign = CString::from_vec_unchecked(vec![1; 128]);
    let result = sign_func(data.as_ptr(), 1866248975, sign.as_ptr());
    assert_ne!(result,-1,"签名失败");
    let use_time = start.elapsed();
    println!("签名用时：{}微秒", use_time.as_micros());

    let start = std::time::Instant::now();
    let result = verify_func(data.as_ptr(), sign.as_ptr(), 1866248975);
    assert_ne!(result,-1,"验签失败");
    let use_time = start.elapsed();
    println!("验证用时：{}微秒", use_time.as_micros());

    return Ok(0);
}

}
