java 0.3.2版 在6核12线程 基础频率 2.5ghz cpu 上 sm2解密耗时 160ms - 220 ms , 有空能不能提升一下性能,拜托了, 谢谢!
SM4 c# 加密,java解密,可以正常解密,但是中文存在乱码
加载JS文件,感觉在springboot打包成jar运行时读取不到文件,不过非常了不起,我也是才知道JDK1.8可用运行JS脚本,思路奇特,大佬有sm2加解密的性能测试数据吗?
不建议直接吞并异常,建议应该与原方法保持一致,吞并异常不知道加解密是否有问题
public static String decrypt(String encryptData, String key, Sm4Options sm4Options) {
if (encryptData == null || encryptData.trim().isEmpty()) return "";
String decryptData = null;
try {
decryptData = (String) invocable.invokeFunction("decrypt", encryptData, key, getOptionsMap(sm4Options));
} catch (ScriptException | NoSuchMethodException e) {
e.printStackTrace();
}
return decryptData;
}
SM3目前只支持String类型的,可以支持byte[] 或文件流吗?JS版本应该是支持的。
简单加密一下居然要花接近4s
@Test
public void testSm2Encrypt() {
String data = "{\"abc\":123}";
String publicKey = "041130412b93ca6ba1b7143d821d363fa12a98bc093dd324e5f47ca7401a75cb8cd098851f40852b5193ca31203f34cc24548dc51ca409933e1d0cd30e4cea6e05";
String privateKey = "16c8160303ed9cf0af3c8d61f93be5e091c2115276bc9152a9cfe2d7b6a903bc";
Long before = System.currentTimeMillis();
String encrypt = Sm2.doEncrypt(data, publicKey);
Long after = System.currentTimeMillis();
System.out.println("加密 " + (after - before) + " ms");
System.out.println("encrypt = " + encrypt);
before = System.currentTimeMillis();
String decrypt = Sm2.doDecrypt(encrypt, privateKey);
after = System.currentTimeMillis();
System.out.println("解密 " + (after - before) + " ms");
System.out.println("decrypt = " + decrypt);
}
使用其他第三方的库对相同数据进行加密只需要大约15ms左右
循环10次测试发现也要大约100-300ms左右
public static void main(String[] args) {
String msg = "159";
// 16 进制字符串,要求为 128 比特
String key = "3124456789abcdeffedcba9876543210";
// 加密,默认使用 pkcs#5 填充,输出16进制字符串
long ens = System.currentTimeMillis();
String encryptData1 = Sm4.encrypt(msg, key);
long ene = System.currentTimeMillis();
System.out.println("encrypt 1 : " + encryptData1);
// 解密,默认使用 pkcs#5 填充,输出 utf8 字符串
long des = System.currentTimeMillis();
String decryptData1 = Sm4.decrypt(encryptData1, key);
long dee = System.currentTimeMillis();
System.out.println("decrypt 1 : " + decryptData1);
System.out.println("encrypt time:" + (dee - des) + "ms" + ". decrypt time:" + (ene-ens) + "ms");
}
out result:
encrypt 1 : a3121e371c1da5e7237d7b18305ce6fd
decrypt 1 : 159
encrypt time:139ms. decrypt time:2582ms
你好,想请问SM2使用的椭圆曲线方程和安全参数,在Java版本中的SM2代码部分没看见。

如题,烦请解答,谢谢
医保局的要求是将签名返回的字节码进行base64编码,我把string转字节后编码的 ,怎么也不对,作者能帮忙吗 联系方式 13104690 (qq微信都是这个)
String msg = "hello world! 我是 antherd.";
String key = "0123456789abcdeffedcba9876543210"; // 16 进制字符串,要求为 128 比特
String encryptData1 = Sm4.encrypt(msg, key); // 加密,默认使用 pkcs#5 填充,输出16进制字符串
System.out.println(encryptData1);
Sm4Options sm4Options2 = new Sm4Options();
sm4Options2.setPadding("none");
String encryptData2 = Sm4.encrypt(msg, key, sm4Options2); // 加密,不使用 padding,输出16进制字符串
System.out.println(encryptData2);
Sm4Options sm4Options3 = new Sm4Options();
sm4Options3.setPadding("none");
byte[] encryptData3 = Sm4.hexToBytes(Sm4.encrypt(msg, key, sm4Options3)); // 加密,不使用 padding,输出转为字节数组
System.out.println(encryptData3);
Sm4Options sm4Options4 = new Sm4Options();
sm4Options4.setMode("cbc");
sm4Options4.setIv("fedcba98765432100123456789abcdef");
String encryptData4 = Sm4.encrypt(msg, key, sm4Options4); // 加密,cbc 模式,输出16进制字符串
System.out.println(encryptData4);
四种加密结果都等于 0e395deb10f6e8a17e17823e1fd9bd98ba9d414a1328bb62fd1a83cdedd7e4dd
sm3 缺少参数
{
key: 'xxxx'
}
您好,能扩展下SM3摘要带公钥和UserId的实现吗?
