示例1: cookie_encode
# 需要導入模塊: from Crypto.Cipher import Blowfish [as 別名]
# 或者: from Crypto.Cipher.Blowfish import block_size [as 別名]
def cookie_encode(self, *ids):
cookie = super(Authentication, self).cookie_encode(*ids)
bs = Blowfish.block_size
iv = Random.new().read(bs)
cipher = Blowfish.new(self.KEY, Blowfish.MODE_CBC, iv)
# pad cookie to block size.
# Cookie is ascii base64 + ':', so we can safely pad with '@'.
missing_bytes = bs - (len(cookie) % bs)
cookie += '@' * missing_bytes
return '%s:%s' % (
b64encode(iv),
b64encode(cipher.encrypt(cookie))
)
return cookie 示例2: encrypt_key
# 需要導入模塊: from Crypto.Cipher import Blowfish [as 別名]
# 或者: from Crypto.Cipher.Blowfish import block_size [as 別名]
