Android签名算法的原理

什么是签名在 apk 中写入一个 “指纹”，指纹写入以后，apk 中有任何修改，都会导致这个指纹无效 Android 系统在安装 apk 进行签名校验时就会不通过，从而保证了安全性 ...

安卓逆向 -- 自吐算法（3DES和AES）

一、3DES源码 String bs= "逆向有你a"; DESedeKeySpec des3key = new DESedeKeySpec(("123456781234567812345678".getBytes(StandardCharsets.UTF_8)));//密钥...

安卓逆向 -- NDK开发实现MD5算法

一、正常SO层校验框架 1、新建一个NativeC++项目 2、新建一个SignatureUtils类，里面写一个原生方法 ...

安卓逆向 -- 算法基础(SHA)

一、SHA算法 SHA由美国标准与技术研究所（NIST）设计并于1993年发表，该版本称为SHA-0，由于很快被发现存在安全隐患，1995年发布了SHA-1。2002年，NIST分别发布了SHA-256、SHA-384、SHA-512，这些算法统称SHA-2。2008年又新增了SHA-224。由于S...

安卓逆向 -- 算法基础(数字签名)

一、数字签名数字签名的基础是公钥和私钥的非对称加密，发送者使用私钥加密消息摘要（签名），接收者使用公钥解密消息摘要以验证签名是否是某个人的。常见的有MD5withRSA，SHA256withRSA 二、Java版 public stat...

安卓逆向 -- 自吐算法（MAC）

一、MAC算法源码 import javax.crypto.Mac import javax.crypto.spec.SecretKeySpec String bs= "逆向有你a"; SecretKeySpec key = new SecretKeySpec("12345"...

安卓逆向 -- 算法基础(Base64与HEX)

一、Base64 1、所有的数据都能被编码为只用65个字符就能表示的文本。标准的Base64每行为76个字符，每行末尾添加一个回车换行符(\r\n)。不论每行是否满76个字符，都要添加一个回车换行符。 2、65字符：A~Z a~z 0~9 + / = URL Base64算法中，为了...

安卓逆向 -- 算法基础(MAC)

一、MAC算法 MAC算法是含有密钥的散列算法，兼容MD和SHA算法，在此基础上添加了密钥支持，因此也被称为Hmac算法，定义在RFC 2014中，分为两大分支MD和SHA分支： MD分支：Hmac-MD2、Hmac-MD4、Hmac-MD5； SHA分支：Hmac-SHA1、Hmac-SHA256...
