JAVA自带的加密算法-MD5\SHA1\BASE64
需要导入jar包:
commons-codec.jar
MD5
String str =
"abc"
;
DigestUtils.md5Hex(str);
SHA1
String str =
"abc"
;
DigestUtils.shaHex(str);
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));
