-------------------------------------------------------------------------------- 1 | # sm-crypto 2 | 3 | 国密算法sm2、sm3和sm4的java版。基于js版本进行封装，无缝兼容js版公私钥加解密。 4 | 5 | > PS: js版：[https://github.com/JuneAndGreen/sm-crypto](https://github.com/JuneAndGreen/sm-crypto) 6 | > 7 | > PS: 小程序版：[https://github.com/wechat-miniprogram/sm-crypto](https://github.com/wechat-miniprogram/sm-crypto) 8 | 9 | ## 如何使用 10 | ### 如何引入依赖 11 | 如果需要使用已发布的版本，在`dependencies`中添加如下依赖 12 | ```xml 13 | 14 | com.antherd 15 | sm-crypto 16 | 0.3.2.1 17 | 18 | ``` 19 | 20 | ## sm2 21 | 22 | ### 获取密钥对 23 | 24 | ```java 25 | Keypair keypair = Sm2.generateKeyPairHex(); 26 | String privateKey = keypair.getPrivateKey(); // 公钥 27 | String publicKey = keypair.getPublicKey(); // 私钥 28 | ``` 29 | 30 | ### 加密解密 31 | 32 | ```java 33 | // cipherMode 1 - C1C3C2，0 - C1C2C3，默认为1 34 | String encryptData = Sm2.doEncrypt(msg, publicKey); // 加密结果 35 | String decryptData = Sm2.doDecrypt(encryptData, privateKey); // 解密结果 36 | ``` 37 | 38 | ### 签名验签 39 | 40 | > ps：理论上来说，只做纯签名是最快的。 41 | 42 | ```java 43 | // 纯签名 + 生成椭圆曲线点 44 | String sigValueHex = Sm2.doSignature(msg, privateKey); // 签名 45 | boolean verifyResult = Sm2.doVerifySignature(msg, sigValueHex, publicKey); // 验签结果 46 | 47 | // 纯签名 48 | Queue pointPool = new LinkedList(Arrays.asList(Sm2.getPoint(), Sm2.getPoint(), Sm2.getPoint(), Sm2.getPoint())); 49 | SignatureOptions signatureOptions2 = new SignatureOptions(); 50 | signatureOptions2.setPointPool(pointPool); // 传入事先已生成好的椭圆曲线点，可加快签名速度 51 | String sigValueHex2 = Sm2.doSignature(msg, privateKey, signatureOptions2); 52 | boolean verifyResult2 = Sm2.doVerifySignature(msg, sigValueHex2, publicKey); // 验签结果 53 | 54 | // 纯签名 + 生成椭圆曲线点 + der编解码 55 | SignatureOptions signatureOptions3 = new SignatureOptions(); 56 | signatureOptions3.setDer(true); 57 | String sigValueHex3 = Sm2.doSignature(msg, privateKey, signatureOptions3); // 签名 58 | boolean verifyResult3 = Sm2.doVerifySignature(msg, sigValueHex3, publicKey, signatureOptions3); // 验签结果 59 | 60 | // 纯签名 + 生成椭圆曲线点 + sm3杂凑 61 | SignatureOptions signatureOptions4 = new SignatureOptions(); 62 | signatureOptions4.setHash(true); 63 | String sigValueHex4 = Sm2.doSignature(msg, privateKey, signatureOptions4); // 签名 64 | boolean verifyResult4 = Sm2.doVerifySignature(msg, sigValueHex4, publicKey, signatureOptions4); // 验签结果 65 | 66 | // 纯签名 + 生成椭圆曲线点 + sm3杂凑（不做公钥推导） 67 | SignatureOptions signatureOptions5 = new SignatureOptions(); 68 | signatureOptions5.setHash(true); 69 | signatureOptions5.setPublicKey(publicKey); // 传入公钥的话，可以去掉sm3杂凑中推导公钥的过程，速度会比纯签名 + 生成椭圆曲线点 + sm3杂凑快 70 | String sigValueHex5 = Sm2.doSignature(msg, privateKey, signatureOptions5); // 签名 71 | boolean verifyResult5 = Sm2.doVerifySignature(msg, sigValueHex5, publicKey, signatureOptions5); // 验签结果 72 | 73 | // 纯签名 + 生成椭圆曲线点 + sm3杂凑 + 不做公钥推 + 添加 userId（长度小于 8192） 74 | // 默认 userId 值为 1234567812345678 75 | SignatureOptions signatureOptions6 = new SignatureOptions(); 76 | signatureOptions6.setHash(true); 77 | signatureOptions6.setPublicKey(publicKey); 78 | signatureOptions6.setUserId("testUserId"); 79 | String sigValueHex6 = Sm2.doSignature(msg, privateKey, signatureOptions6); // 签名 80 | boolean verifyResult6 = Sm2.doVerifySignature(msg, sigValueHex6, publicKey, signatureOptions6); // 验签结果 81 | ``` 82 | 83 | ### 获取椭圆曲线点 84 | 85 | ```java 86 | Point point = Sm2.getPoint(); // 获取一个椭圆曲线点，可在sm2签名时传入 87 | ``` 88 | 89 | ## sm3 90 | 91 | ```java 92 | String hashData = Sm3.sm3("abc"); // 杂凑 93 | ``` 94 | 95 | ## sm4 96 | 97 | ### 加密 98 | 99 | ```java 100 | String msg = "hello world! 我是 antherd."; 101 | String key = "0123456789abcdeffedcba9876543210"; // 16 进制字符串，要求为 128 比特 102 | 103 | String encryptData1 = Sm4.encrypt(msg, key); // 加密，默认使用 pkcs#5 填充，输出16进制字符串 104 | 105 | Sm4Options sm4Options2 = new Sm4Options(); 106 | sm4Options2.setPadding("none"); 107 | String encryptData2 = Sm4.encrypt(msg, key, sm4Options2); // 加密，不使用 padding，输出16进制字符串 108 | 109 | Sm4Options sm4Options3 = new Sm4Options(); 110 | sm4Options3.setPadding("none"); 111 | byte[] encryptData3 = Sm4.hexToBytes(Sm4.encrypt(msg, key, sm4Options3)); // 加密，不使用 padding，输出转为字节数组 112 | 113 | Sm4Options sm4Options4 = new Sm4Options(); 114 | sm4Options4.setMode("cbc"); 115 | sm4Options4.setIv("fedcba98765432100123456789abcdef"); 116 | String encryptData4 = Sm4.encrypt(msg, key, sm4Options4); // 加密，cbc 模式，输出16进制字符串 117 | ``` 118 | 119 | ### 解密 120 | 121 | ```java 122 | String encryptData = "0e395deb10f6e8a17e17823e1fd9bd98a1bff1df508b5b8a1efb79ec633d1bb129432ac1b74972dbe97bab04f024e89c"; // 加密后的 16

Sm4Options sm4Options6 = new Sm4Options(); 128 | sm4Options6.setPadding("none"); 129 | String decryptData6 = Sm4.decrypt(encryptData, key, sm4Options6); // 解密，不使用 padding，输出 utf8 字符串 130 | 131 | Sm4Options sm4Options7 = new Sm4Options(); 132 | sm4Options7.setPadding("none"); 133 | byte[] decryptData7 = Sm4.utf8ToArray(Sm4.decrypt(encryptData, key, sm4Options7)); // 解密，不使用 padding，输出转为字节数组 134
