接下来,我们可以使用以下代码来解析RSA公钥: fromCrypto.PublicKeyimportRSA# 读取公钥文件withopen('public_key.pem','rb')asf:public_key_data=f.read()# 解析公钥public_key=RSA.import_key(public_key_data)# 获取公钥的模数和指数modulus=public_key.n exponent=public_key.eprint("Modulus:",modulus)prin...
而在RSA密码体系中,加密过程与解密过程明文直接参与运算,这里要求秘文与生成的随机数保持一致, 在这里采用ASCII码的方式将其转化为数字列表,进而转化成字符串参与运算。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 # 将字符串转成ASCIIdefTransfer_To_Ascii(messages):result=[]formessageinmessages:result....

3.1.2 使用RSA进行加密与解密操作 RSA不仅可以用于密钥交换,还可以用于数据加密。以下是如何使用Python和cryptography库进行RSA加密和解密: # 加密过程 # 假设我们已有一个待加密的消息和一个公钥 message = b"This is a top-secret message." public_key_pem = pem_public_key # 从上一步骤获取的公钥PEM格式数...
functiongetEncryptedPassword(pwd,n,i,t){varkey_to_encode=newRSAKeyPair(n,i,t);returnencryptedString(key_to_encode,pwd)} 其中pwd就是明文密码,n,i,t是用来获取key_to_encode的参数,它们三个的值都可以在主页中找到。 3.3 JS代码 setMaxDigits()貌似是生成密文的最大位数, 计算公式n ** 2 / 16。
