+# 密码加密
+
+严格来讲，密码加密不属于 [权限认证] 的范畴，但是对于大多数系统来讲，密码加密又是安全认证不可或缺的部分，
+所以，应大家要求，`sa-token`在`v1.14版本`添加密码加密模块，该模块非常简单，仅仅封装了一些常见的加密算法
+
+
+
+### 摘要加密
+md5、sha1、sha256
+``` java
+// md5加密 
+SaSecureUtil.md5("123456");
+
+// sha1加密 
+SaSecureUtil.sha1("123456");
+
+// sha256加密 
+SaSecureUtil.sha256("123456");
+
+// md5加盐加密: md5(md5(str) + md5(salt)) 
+SaSecureUtil.md5BySalt("123456", "salt");
+```
+
+
+### 对称加密
+AES加密
+``` java
+// 定义秘钥和明文
+String key = "123456";
+String text = "sa-token 一个轻量级java权限认证框架";
+
+// 加密 
+String ciphertext = SaSecureUtil.aesEncrypt(key, text);
+System.out.println("AES加密后：" + ciphertext);
+
+// 解密 
+String text2 = SaSecureUtil.aesDecrypt(key, ciphertext);
+System.out.println("AES解密后：" + text2);
+```
+
+
+### 非对称加密
+RSA加密
+``` java
+// 定义私钥和公钥 
+String privateKey = "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";
+String publicKey = "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDvsJrdNacJvZRzHauwPIJBIoJNFyjH47/uCIwBYVgkok3j+3bZZ3HhSW5Fsb23O0KN3wjqcJn3LJMFHN1UoMoiZDSQ7PYrz275bfCFNm2fjwQ8WMUgiRa4KLlTqQK/Gq/2+oDbmE4tb7dxZBrUowAhW9NNv+vESlE8nvP7XXFYpQIDAQAB";
+
+// 文本
+String text = "sa-token 一个轻量级java权限认证框架";
+
+// 使用公钥加密
+String ciphertext = SaSecureUtil.rsaEncryptByPublic(publicKey, text);
+System.out.println("公钥加密后：" + ciphertext);
+
+// 使用私钥解密
+String text2 = SaSecureUtil.rsaDecryptByPrivate(privateKey, ciphertext);
+System.out.println("私钥解密后：" + text2); 
+```
+
+你可能会有疑问，私钥和公钥这么长的一大串，我怎么弄出来，手写吗？当然不是，调用以下方法生成即可
+``` java
+// 生成一对公钥和私钥，其中Map对象 (private=私钥, public=公钥)
+System.out.println(SaSecureUtil.rsaGenerateKeyPair());
+```
+
+
+### Base64编码与解码
+``` java
+// 文本
+String text = "sa-token 一个轻量级java权限认证框架";
+
+// 使用Base64编码
+String base64Text = SaBase64Util.encode(text);
+System.out.println("Base64编码后：" + base64Text);
+
+// 使用Base64解码
+String text2 = SaBase64Util.decode(base64Text);
+System.out.println("Base64解码后：" + text2); 
+```
