test.py文件是性能测试文件，运行后可以打印测试结果（1000次加解密结果）：

test_rsa1024_pycryptodome 5.4410345(s)
test_rsa2048_pycryptodome 5.317147899999999(s)
test_rsa1024_cryptography 0.6586130000000008(s)
test_rsa2048_cryptography 0.6512908(s)

由结果可知cryptography比pycryptodome库快接近10倍，达到了微秒级别。（注意：受电脑本身性能影响，不同电脑测试结果可能有差异。）

main.py是主函数，运行后启动一个http服务器

• 本地浏览器访问http://localhost:5000/login，可测试前端jsencrypt库与后端pycryptodome库

• 本地浏览器访问http://localhost:5000/test_login，可测试前端jsrsasign库与后端cryptography库

• 基于前后端测试，也能发现cryptography比pycryptodome至少快3倍左右，下面是控制台打印结果： 发送多次登录请求后，发现cryptography解密时间稳定在0.6ms左右，pycryptodome解密时间稳定在6ms左右，此结果与timeit中测试结果10倍性能差距相符合。
