- The first stage of generating our token is creating a key that is unique for each user using the same hashhmac function. This key is generated using the user id and a global secret key constant. This key is then used to generate the final authentication token by combining the previous key and personal information about the user such as the id.
- A Time-based One-time Password Algorithm (TOTP) is an algorithm that computes a one-time password from a shared secret key and the current time. It is the cornerstone of Initiative For Open Authentication (OATH) and is used in a number of two factor authentication systems.
Encrypt message with key K1A (you probably want to use HMAC or AEAD scheme here, we don't want compromised/faulty server to serve random data). How much messages to save with one key is up to you (I'd argue that 5min is good, but configure to your liking). Generate new key K2 and save: K1B xor K2. Forget K1,K1A,K1B and Make K1:=K2.
Message authentication using cryptographic hash functions in python can be achieved through the HMAC mechanism. We can use HMAC with multiple iterable hash functions such as MD5, SHA-1 in combination with a secret shared key.
The basic idea is to secure our data, by generating a cryptographic hash of the actual data combined with a shared secret key. The final result is sent without the secret key but the resulting hash can be used to check the transmitted or stored message.

Used to update the hmac object using the given message. Messages will get appended if you call this method more than once.
hmac.digest()
Return the digest of the bytes passed to the update() method so far.
hashlib.hexdigest()
Like digest() except the digest is returned as a string twice the length containing only hexadecimal digits. This may be used to exchange the value safely in email or other non-binary environments.
haslib.copy()
Return a copy (“clone”) of the hmac object.

Example1
Creating a hash, using the default MD5 hash algorithm.
Output
As SHA1 is considered more secure than MD5 algorithm and if you are thinking of running the above program using SHA1 algorithm. Just modify the algorithm name in this line,
my_hmac = hmac.new(update_bytes, password,hashlib.sha1)
and our result will be something like:
Hmac Key Length
The first digest: b'xc3Txe7[xc8xa3O/$xbd`Axadx07dxe8xaexa2!xb4'
Applications
Generate Codeigniter 3 Hmac Key Download
HMAC authentication mechanism can be used in any place where security is important like public network services. For example, in public network we are sending an important file/data through a pipe or socket, that file/data should be signed and then the signature should be tested before the data is used.
