【用python加密解密MD5】

已知一个999999以下的数的md5值,通过撞库的方式解密:

将999999以下的数的md5值存入md5.txt:

import hashlib

with open('md5.txt', 'w') as f:
    print('正在写入。。。')
    for i in range(0, 999999):
        md5 = hashlib.md5(str(i).encode()).hexdigest() + '\n'
        
        f.write(md5)
    print('写入完成。')

撞库解密:

def md5decrypt(num: str):
    with open('md5.txt', 'r') as f:
        result = 0
        for line in f:
            line = line.split('\n')
            if num == line[0]:
                print('解密成功,密文为:', result)
                return result
            else:
                result += 1
        print('解密失败!')
        return None

if __name__ == '__main__':
    r = md5decrypt('d3e4029427aa766ffa42fd454b28d3b4')
    if r:
    	print('解密成功:', r)
    else:
        print('解密失败!')
