1.AES-128-ECB表示使用AES(Advanced Encryption Standard)算法,密钥长度为128位,工作模式为ECB(Electronic Codebook)的一种对称加密方式。
其中:
- AES是一种常用的对称加密算法,被广泛地应用于各种信息安全场景中。
- 128表示密钥长度为128位(16字节)。AES支持的密钥长度还有192位和256位。
- ECB代表电子密码本(Electronic Codebook)模式,是最基本的一种工作模式,将明文分成固定大小的块,每个块独立地进行加密。ECB模式存在明文块重复可导致密文块重复的风险。
综上,AES-128-ECB意思是:
使用128位密钥的AES算法,以ECB电子密码本模式来对明文进行分组加密。
它提供了基本的加密保护,但相比其他模式如CBC,CFB等,ECB模式在许多场景下安全性较弱,应谨慎使用。
2.MD5接口加密通常指在接口请求中使用MD5算法对请求参数进行加密,以保证参数不被篡改的一种简单安全机制。
具体做法是:
1. 接口请求方和服务端双方约定一个密钥,例如"123456"。
2. 当请求方需要请求某个接口时,将所有请求参数按照约定的顺序拼接成字符串,例如"a=1&b=2"。
3. 对这个参数字符串以及密钥一起做MD5哈希运算,得到一个32位长度的MD5值,例如"e10adc3949ba59abbe56e057f20f883e"。
4. 在接口请求中将这个MD5值作为参数传给服务端。
5. 服务端收到请求后,使用同样的密钥和方法计算MD5值,与请求附带的MD5值比较。
6. 如果一致,则证明参数没有被篡改,然后继续处理请求。
这样通过MD5摘要验证,可以防止参数在传输中被非法修改。但MD5仅能防篡改,不能防止披露,所以需要与HTTPS等其他加密传输手段配合使用。
下面请看示例
这个是接口文档说明
签名方式：
- 将所有参数（注意是所有参数），除去sign本身，按参数名字母ASCII升序排序；
- 将所有参数按照key=value的方式凭借起来；
- 将秘钥和第2步的字符串拼接起来；
- 将这个字符串MD5加密（32位小写）得到sign，
- sign作为参数传递过来
