# Encryption

#### 项目介绍
RSA加解密算法

#### 使用说明

1. 生成公钥和私钥

    RSAEncrypt.genKeyPair(filepath);  
        
2. 公钥加密私钥解密 

    //公钥加密过程  
    byte[] cipherData = RSAEncrypt.encrypt(RSAEncrypt.loadPublicKeyByStr(RSAEncrypt.loadPublicKeyByFile(filepath)), plainText.getBytes());  
    String cipher = Base64.encode(cipherData);  
    //私钥解密过程  
    byte[] res = RSAEncrypt.decrypt(RSAEncrypt.loadPrivateKeyByStr(RSAEncrypt.loadPrivateKeyByFile(filepath)), Base64.decode(cipher));  
    String restr = new String(res); 
    
3. 私钥加密公钥解密过程

    //私钥加密过程  
    byte[] cipherData = RSAEncrypt.encrypt(RSAEncrypt.loadPrivateKeyByStr(RSAEncrypt.loadPrivateKeyByFile(filepath)),plainText.getBytes());  
    String cipher = Base64.encode(cipherData);  
    //公钥解密过程  
    byte[] res = RSAEncrypt.decrypt(RSAEncrypt.loadPublicKeyByStr(RSAEncrypt.loadPublicKeyByFile(filepath)), Base64.decode(cipher));  
    String restr = new String(res); 

4. 私钥签名过程

    String signstr = RSASignature.sign(content,RSAEncrypt.loadPrivateKeyByFile(filepath));  
 
5. 公钥校验签名

    RSASignature.doCheck(content, signstr, RSAEncrypt.loadPublicKeyByFile(filepath));
