aardio 范例: sha-256

//SHA-256
import crypt.rsa;

//直接返回 16 进制大写结果
var hex = crypt.sha256("test",true);

//用 crypt.rsa() 或 crypt(,0x18/*_PROV_RSA_AES*/) 创建对象才能支持 SHA-256 算法,
var rsa  = crypt.rsa()

//哈希对象
var sha256 = crypt.rsa().createHashBySha256(); 
sha256.hashData("test");//添加数据
var hex = sha256.getHexValue();  

//计算文件哈希
var rsa  = crypt.rsa();
var hex = rsa.hashFile("\sha-256.aardio",true,0x800C/*_CALG_SHA_256*/) 
print( hex );
