前言💞💞💞 安全算法:公开密钥加密之RSA算法 公开密钥加密(又称“非对称加密”)是加密和解密使用不同密钥的一种加密方法。包括公开密钥和私有密钥(成对生成的,网上有工具网站)。 公开密钥(public key,后面简称P):加密用的密钥 私有密钥(secret key,后面简称S):解密用的密钥 背景💖💖💖 RSA公钥加密算法...

One of the core decisions in this field is the key size. Most people have heard that1024 bit RSA keys have been crackedand are not used any more for web sites orPGP. The next most fashionable number after 1024 appears to be 2048, but a lot of people have also been skipping that and...

第一种: pem格式文件 或者 base64的 public key 一个pem格式的公钥文件,其中保存的公钥信息是base64编码的字符串,这个用iOS 系统sercurity.framework的api就不能读取。 后台经常会给一个xxx.pem的文件. 里面的内容用sublime打开就如上所示. 下面是pem内容示例(ps: 每行64个字符) ...
