五、测试验证
六、源码地址
对于程序项目来说,企业间业务对接,少不了http api接口公网对接。而http接口公网对接就必须做到接口安全认证,防止接口或数据被拦截窃取,破解泄露商业信息,甚至黑客攻击。此时就必须做安全措施,如加白名单、数字安全认证证书(https)等。其中,RSA非对称加密进行加签和验证是常用的一种。RSA公钥加密算法是1977年由Ron Rivest、Adi Shamirh和LenAdleman在(美国麻省理工学院)开发的。RSA取名来自开发他们三者的名字。RSA是目前最有影响力的公钥加密算法,它能够抵抗到目前为止已知的所有密码攻击,已被ISO推荐为公钥数据加密标准。RSA算法详细请看密码学:RSA加密算法详解_大鱼-CSDN博客_rsa加密算法。
这里大致认识下RSA算法和数字安全认证https:
RSA是目前最有影响力和最常用的公钥加密算法,它能够抵抗到目前为止已知的绝大多数密码攻击,已被ISO推荐为公钥数据加密标准。
今天只有短的RSA钥匙才可能被强力方式破解。但在分布式计算和量子计算机理论日趋成熟的今天,RSA加密安全性收到了挑战和质疑。
RSA算法基于一个十分简单的数论事实:将两个大质数相乘十分容易,但是想要对其乘积进行因式分解缺及其困难,因此可以将乘积公开作为加密密钥。
可以自己实现,无需购买,算法公开。
使用HTTPS协议可认证用户和服务器,确保数据发送到正确的客户机和服务器。
HTTPS协议是由SSL+HTTP协议构建的可进行加密传输、身份认证的网络协议,要比HTTP协议安全,可防止数据在传输过程中不被窃取、改变,确保数据的完整性。
HTTPS是现行框架下最安全的解决方案,虽然不是觉得安全,但它增加了中间人攻击的成本。
SSL的专业证书需要购买,功能越强大的证书费用越高
相同的网络环境下,HTTPS协议会使页面的加载时间延长50%,增加10%-20%的耗电。此外,HTTPS协议还会影响缓存,增加数据开销和功耗。
HTTPS协议的安全性是有范围的,在黑客攻击、拒绝服务攻击、服务器劫持等方面几乎起不到什么作用。
最关键的是,SSL证书的信用链体系并不安全。特别是在某些国家可以控制CA根证书的情况下,中间人攻击一样可行。
最后以对象的序列化后的json字符串传输。
交互流程图,如下:
描述:A企业、B企业先生成公私钥,然后互相交换公钥。调用方调用接口前,使用自己的私钥加密; 被调用方接收数据前使用调用方给的公钥解密,解密成功允许调用接口逻辑处理返回数据;解密失败(鉴权失败)不允许调用接口。
如:openssl genrsa -out rsa_private_key.pem 1024
命令格式:openssl genras -out 私钥文件名 1024
实际操作如下(这里使用git bash界面):
生成一个由”----BEGIN PRIVATE KEY-----”开头,由”-----END PRIVATE KEY-----”结尾的rsa_private_key.pem文件,这就是私钥文件。
如:openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
命令格式:openssl rsa -in私钥文件名 -pubout -out 公钥文件名
生成一个由”----BEGIN PRIVATE KEY-----”开头,由”-----END PRIVATE KEY-----”结尾的rsa_public_key.pem文件,这就是公钥文件。
如:openssl pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt > rsa_private_key_pkcs8.pem
命令格式:openssl pkcs8 -topk8 -inform PEM -in 私钥文件名 -outform PEM -nocrypt > pkcs8格式私钥文件名
实际操作如下:
生成一个由”----BEGIN PRIVATE KEY-----”开头,由”-----END PRIVATE KEY-----”结尾的rsa_private_key_pkcs8.pem文件,这就是适配java语言开发的私钥文件(第一步生成的私钥是pkcs1格式的文件,像php可以直接使用。但java使用就必须转换成pkcs8格式的文件内容)。
描述:可以发现第三步和第一步都是私钥,他们都是由”----BEGIN PRIVATE KEY-----”开头,由”-----END PRIVATE KEY-----”结尾,密钥内容却不相同。在java代码里,我们读取的密钥体是不包含开头和结尾的,因此我们把第二部和第三步的pem文件去掉开头结尾重新存储下。
