读取手机号，并生成这些手机号的MD5哈希值。生成的哈希值会保存到两个不同的TXT文件中，一个文件包含手机号和其对应的MD5哈希值，另一个文件只包含MD5哈希值。

import hashlib

def md5_hash(text):
    return hashlib.md5(text.encode()).hexdigest()

def main():
    input_file = input("请输入要处理的TXT文件名：")
    output_file_phone_md5 = input("请输入要保存手机号对应MD5哈希值的TXT文件名：")
    output_file_md5 = input("请输入要保存MD5哈希值的TXT文件名：")

    with open(input_file, 'r', encoding='utf-8') as file:
        phone_numbers = file.readlines()

    phone_md5_pairs = {}
    hashed_phone_numbers = []

    for number in phone_numbers:
        number = number.strip()
        hashed_number = md5_hash(number)
        phone_md5_pairs[number] = hashed_number
        hashed_phone_numbers.append(hashed_number)

    with open(output_file_phone_md5, 'w', encoding='utf-8') as file:
        for phone, md5 in phone_md5_pairs.items():
            file.write(f"{phone}: {md5}\n")

    with open(output_file_md5, 'w', encoding='utf-8') as
