WebApr 12, 2024 · A hash object has the following attributes: HMAC.digest_size ¶ The size of the resulting HMAC digest in bytes. HMAC.block_size ¶ The internal block size of the hash algorithm in bytes. New in version 3.4. HMAC.name ¶ The canonical name of this HMAC, always lowercase, e.g. hmac-md5. New in version 3.4. WebUse the MD5 Algorithm in Python. To use the md5 algorithm, we will use the md5 () constructor and feed the hash object with byte-like objects using the update () method or pass the data as a parameter of the constructor. To obtain the hash value, use the digest () method, which returns a bytes object digest of the data fed to the hash object.
