Python进行RSA安装加密

时间：2022-01-16 07:54:50

一、下载ez_setup.py（http://peak.telecommunity.com/dist/ez_setup.py）

二、用python解释执行它 （如使用IDLE打开该py文件，按F5解释执行）

三、安装完成后，会在scripts文件夹下生成几个exe可执行文件。（如： D:\Python27\Scripts目录下）

四、可以把之前下载的文件rsa-3.1.1-py2.7.egg拷贝到D:\Python27\Scripts目录下, 然后在cmd中切换到D:\Python27\Scripts目录下，执行egg文件：easy_install.exe rsa-3.1.1-py2.7.egg

    f = open(filename)

    n = int(f.read(),16)

    print('*'*77)

    print(filename)

    print(hex(n))

    print('*'*77)

    return (n)

def my_RSA_encrypt(src, d, n):

    x = pow(src, d, n)

    print('*'*77)

    print("Encrypted Data is:")

    print(hex(x))

    print('*'*77)

    return x

def my_RSA_decrypt(src, e, n):

    y = pow(src, e, n)

    print('*'*77)

    print("Decrypted Data is:")

    print(hex(y))

    print('*'*77)

    return y

fname = path + "\\Firm_N.txt"

plaintData = GetDataFromFile(fname)

fname = path + "\\Manuf_private_d.txt"

d = GetDataFromFile(fname)

n = GetDataFromFile(fname)

encryptedData = my_RSA_encrypt(plaintData, d, n)
