Python Hmac Module

HMAC message authentication — new, digest, hexdigest, compare_digest. This category documents 5 Python hmac module entries, and each page gives you the full syntax, the parameter list, the return value, and a runnable example. The entries include: hmac.new(), hmac.digest(), hmac.hexdigest(), hmac.update(), hmac.compare_digest(). hmac.new() creates a new HMAC object for message authentication. hmac.digest() returns the digest as bytes. hmac.hexdigest() returns the digest as a hexadecimal string. hmac.update() updates the HMAC object with additional data. hmac.compare_digest() constant-time comparison to prevent timing attacks. You can also search across every category from the search page, browse the complete A–Z index, or try any example in the Python playground. Python Reference documents 978+ functions, methods, and modules across 114 categories of the standard library, and every entry in this Hmac Module category follows the same format — syntax first, then what it does, the parameters it accepts, what it returns, and a working code example — so once you have read one page you can read them all.
