如何在不使用javascript或CSS的情况下更改以下标记中title属性的样式,因为我将HTML插入到其他不可编辑的doc中的特定位置.
<span title = "This is information"> This is a test
</span>

from Crypto.PublicKey import RSA
#Write key to file
key = RSA.generate(4096)
privateKey = key.exportKey()
file1 = open('keyfile.pem', 'wb')
file1.write(privateKey)
file1.close()
#Read key from file
file2 = open('keyfile.pem', 'rb')
key = RSA.importKey(file2.read()) #this is the problem

错误是“不支持 RSA 密钥格式”。任何人都可以帮助我从文件中写入/读取私钥的最佳方法吗?
