Question

我有这个公钥和私钥，我该如何解码？

谢谢。

Answer 1

基本上任何识别DER结构的ASN.1解码器都可以...

有关免费的JavaScript版本，请参阅 https://lapo.it/asn1js/

Answer 2

(这使用Python 3)

从开始菜单打开CMD(窗口)或从启动板的实用程序页面打开终端(mac)。类型：

pip install pycrypto

如果这给您带来错误，请尝试：

pip3 install pycrypto

(您可能不必执行此操作)在 IDLE 窗口中选择"打开模块"，然后键入crypto。如果它给你一个错误，那么你很好。然后，将crypto重命名为带大写字母的Crypto。

返回python并键入以下内容(在编辑窗口中)：

from Crypto.PublicKey import RSA
key = RSA.importKey('file.pem') # where file.pem is where your keys are stored, in the format you had in your question
public = key.publickey()
output = public.encrypt('data'.encode('utf-8'),32) # 'data' is a placeholder
output = key.decrypt('data'.encode('utf-8'))

输出将bytes，以转换为十六进制：

print(output.hex())
