1. [代码]MD5
String str = "abc";
DigestUtils.md5Hex(str);
//附.net生成MD5的方法,生成内容跟java一致:
String str = "abc";
FormsAuthentication.HashPasswordForStoringInConfigFile(str, "MD5");
2. [代码]SHA1
String str = "abc";
DigestUtils.shaHex(str);
//附.net生成SHA1的方式,生成内容跟java一致:
String str = "abc";
FormsAuthentication.HashPasswordForStoringInConfigFile(str, "SHA1");
3. [代码]BASE64
//加密
String str= "abc"; // abc为要加密的字符串
byte[] b = Base64.encodeBase64(str.getBytes(), true);
System.out.println(new String(b));
//解密
String str = "YWJj"; // YWJj为要解密的字符串
byte[] b = Base64.decodeBase64(str.getBytes());
System.out.println(new String(b));
