python 生成密钥自定义函数

 

有些应用需要一些 secret_key和access_key,下面是生成随机的字符串

mport os
import base64
import random
import time
import hashlib

# 方法一
tmp = os.urandom(21)
secret_key = base64.b64encode(tmp)
print(secret_key)

# 方法二
def get_random_secret_key(length=12, allowed_chars=None, secret_key=None):
    """
    生成随机字符串
    :param length: 随机字符串长度
    :param allowed_chars: 随机字符串字符取值范围
    :param secret_key: 生成随机字符串的随机字符串
    :return:
    """
    if secret_key is None:
        secret_key = "n&^-9#k*-6pwzsjt-qsc@s3$l46k(7e%f80e7gx^f#vouf3yvz"
    if allowed_chars is None:
        allowed_chars = 'abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*(-_=+)'

    random.seed(
        hashlib.sha256(
            ("%s%s%s" % (
                random.getstate(),
                time.time(),
                secret_key)).encode('utf-8')
        ).digest())
    ret = ''.join(random.choice(allowed_chars) for i in range(length))
    return ret

#
a = get_random_secret_key(50)
print(a)
