encryption

简单的封装了JAVA的RSA和AES加密,RSA和AES最常用的两个加密算法,直接调用加密和解密方法即可。非常简单

RSA

        String[] key = RSA.getKey();
        String data;

        System.out.println("--------------私钥加密公钥解密过程-------------------");
        data = "私钥加密公钥解密过程";
        String encrypt = RSA.privateEncrypt(key[0], data);
        String decrypt = RSA.publicDecrypt(key[1], encrypt);
        System.out.println("原文：" + data);
        System.out.println("密文：" + encrypt);
        System.out.println("解密：" + decrypt);
        System.out.println();

        System.out.println("--------------公钥加密私钥解密过程-------------------");
        data = "公钥加密私钥解密过程";
        encrypt = RSA.publicEncrypt(key[1], data);
        decrypt = RSA.privateDecrypt(key[0], encrypt);
        System.out.println("原文：" + data);
        System.out.println("密文：" + encrypt);
        System.out.println("解密：" + decrypt);
        System.out.println();

AES

        String key = AES.getKey();

        System.out.println("--------------AES ECB加密解密过程-------------------");
        String data = "AES ECB加密解密过程";
        String encode =  AES.encrypt(key, data);
        System.out.println("秘钥:" + key);
        System.out.println("原文:" + data);
        System.out.println("加密:" + encode);
        System.out.println("解密:" + AES.decrypt(key, encode));
        System.out.println();

        System.out.println("--------------AES CBC加密解密过程-------------------");
        data = "AES CBC加密解密过程";
        encode = AES.encrypt(key, data, "1234567890123456");
        System.out.println("秘钥:" + key);
        System.out.println("原文:" + data);
        System.out.println("加密:" + encode);
        System.out.println("解密:" + AES.decrypt(key, encode, "1234567890123456"));
        System.out.println();

Kotlin

    val keyPairGen = RSAEncrypt.genKeyPair()
    val privateKey = RSAEncrypt.strToPrivateKey(keyPairGen!![0])
    val publicKey = RSAEncrypt.strToPublicKey(keyPairGen[1])

    println("--------------私钥加密公钥解密过程-------------------")
    var data = "私钥加密公钥解密过程"
    var encrypt = RSAEncrypt.encrypt(privateKey, data.toByteArray())
    var decrypt = RSAEncrypt.decrypt(publicKey, encrypt!!)
    println("原文：$data")
    println("密文：${Base64.encode(encrypt)}")
    println("解密：${String(decrypt!!)}")
    println()

    println("--------------公钥加密私钥解密过程-------------------")
    data = "公钥加密私钥解密过程"
    encrypt = RSAEncrypt.encrypt(publicKey, data.toByteArray())
    decrypt = RSAEncrypt.decrypt(privateKey, encrypt!!)
    println("原文：$data")
    println("密文：${Base64.encode(encrypt)}")
    println("解密：${String(decrypt!!)}")
    println()

    println("--------------私钥签名公钥验签过程-------------------")
    data = "私钥签名公钥验签过程"
    var sign = RSASignature.sign(data, keyPairGen[0])
    println("原文：$data")
    println("签名串：$sign")
    println("验签结果：${RSASignature.doCheck(data, sign!!, keyPairGen[1])}")
    println()
    
    val key = AES.genKey()

    println("--------------AES ECB加密解密过程-------------------")
    var data = "AES ECB加密解密过程"
    var encode = AES.ecbEncrypt(data, key!!)
    println("原文:" + data)
    println("密文:" + encode!!)
    println("解密:" + AES.ecbDecrypt(encode, key)!!)
    println()

    println("--------------AES CBC加密解密过程-------------------")
    data = "AES ECB加密解密过程"
    encode = AES.cbcEncrypt(data, key, "这里只取前16个字节")
    println("原文:" + data)
    println("密文:" + encode!!)
    println("解密:" + AES.cbcDecrypt(encode, key, "这里只取前16个字节")!!)
    println()
