• jsencrypt 加密怎么用 Python 的 rsa 库实现
• python 3 实现 js 中 JSEncrypt encrypt 方法，rsa 模块根据字符串公钥生成加密字符串
• rsa 字符串格式公钥转换 python rsa 库可识别的公钥形式

大致程序展示：

import base64
from Crypto.Cipher import PKCS1_v1_5 as Cipher_pksc1_v1_5
from Crypto.PublicKey import RSA

def encrpt(password, public_key):
    rsakey = RSA.importKey(public_key)
    cipher = Cipher_pksc1_v1_5.new(rsakey)
    cipher_text = base64.b64encode(cipher.encrypt(password.encode()))
    return cipher_text.decode()

if __name__ == '__main__':
    public_key = """-----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC9iE3T355IktI5kG+XMrh8k71L
0aqDTG5YRh3hT+0ouS3hxufPvLEN8eUmPFdYXJ6RU7tezX84xGf58t0pLo+TV6Rq

-----END PUBLIC KEY-----
"""
    pass_word = '123456'
    print(encrpt(pass_word, public_key))

结果：
