.. _hashlib-blake2:
:mod:`hashlib` --- BLAKE2 hash functions
========================================
.. module:: hashlib
:synopsis: BLAKE2 hash function for Python
.. sectionauthor:: Dmitry Chestnykh
.. index::
single: blake2b, blake2s
BLAKE2_ is a cryptographic hash function, which offers highest security while
being as fast as MD5 or SHA-1, and comes in two flavors:
* **BLAKE2b**, optimized for 64-bit platforms and produces digests of any size
between 1 and 64 bytes,
* **BLAKE2s**, optimized for 8- to 32-bit platforms and produces digests of any
size between 1 and 32 bytes.
BLAKE2 supports **keyed mode** (a faster and simpler replacement for HMAC_),
**salted hashing**, **personalization**, and **tree hashing**.
Hash objects from this module follow the API of standard library's
:mod:`hashlib` objects.
Module
======
Creating hash objects
---------------------
New hash objects are created by calling constructor functions:
.. function:: blake2b(data=b'', digest_size=64, key=b'', salt=b'', \
person=b'', fanout=1, depth=1, leaf_size=0, node_offset=0, \
node_depth=0, inner_size=0, last_node=False)
.. function:: blake2s(data=b'', digest_size=32, key=b'', salt=b'', \
person=b'', fanout=1, depth=1, leaf_size=0, node_offset=0, \
node_depth=0, inner_size=0, last_node=False)
These functions return the corresponding hash objects for calculating
BLAKE2b or BLAKE2s. They optionally take these general parameters:
* *data*: initial chunk of data to hash, which must be interpretable as buffer
of bytes.
* *digest_size*: size of output digest in bytes.
* *key*: key for keyed hashing (up to 64 bytes for BLAKE2b, up to 32 bytes for
BLAKE2s).
* *salt*: salt for randomized hashing (up to 16 bytes for BLAKE2b, up to 8
bytes for BLAKE2s).
* *person*: personalization string (up to 16 bytes for BLAKE2b, up to 8 bytes
for BLAKE2s).
The following table shows limits for general parameters (in bytes):
======= =========== ======== ========= ===========
Hash digest_size len(key) len(salt) len(person)
======= =========== ======== ========= ===========
BLAKE2b 64 64 16 16
BLAKE2s 32 32 8 8
======= =========== ======== ========= ===========
.. note::
BLAKE2 specification defines constant lengths for salt and personalization
parameters, however, for convenience, this implementation accepts byte
strings of any size up to the specified length. If the length of the
parameter is less than specified, it is padded with zeros, thus, for
example, ``b'salt'`` and ``b'salt\x00'`` is the same value. (This is not
the case for *key*.)
These sizes are available as module `constants`_ described below.
Constructor functions also accept the following tree hashing parameters:
* *fanout*: fanout (0 to 255, 0 if unlimited, 1 in sequential mode).
* *depth*: maximal depth of tree (1 to 255, 255 if unlimited, 1 in
sequential mode).
* *leaf_size*: maximal byte length of leaf (0 to 2**32-1, 0 if unlimited or in
sequential mode).
* *node_offset*: node offset (0 to 2**64-1 for BLAKE2b, 0 to 2**48-1 for
BLAKE2s, 0 for the first, leftmost, leaf, or in sequential mode).
* *node_depth*: node depth (0 to 255, 0 for leaves, or in sequential mode).
* *inner_size*: inner digest size (0 to 64 for BLAKE2b, 0 to 32 for
BLAKE2s, 0 in sequential mode).
* *last_node*: boolean indicating whether the processed node is the last
one (`False` for sequential mode).

Examples
========
Simple hashing
--------------
To calculate hash of some data, you should first construct a hash object by
calling the appropriate constructor function (:func:`blake2b` or
:func:`blake2s`), then update it with the data by calling :meth:`update` on the
object, and, finally, get the digest out of the object by calling
:meth:`digest` (or :meth:`hexdigest` for hex-encoded string).
>>> from hashlib import blake2b
>>> h = blake2b()
>>> h.update(b'Hello world')
>>> h.hexdigest()
'6ff843ba685842aa82031d3f53c48b66326df7639a63d128974c5c14f31a0f33343a8c65551134ed1ae0f2b0dd2bb495dc81039e3eeb0aa1bb0388bbeac29183'
As a shortcut, you can pass the first chunk of data to update directly to the
constructor as the first argument (or as *data* keyword argument):
>>> from hashlib import blake2b
>>> blake2b(b'Hello world').hexdigest()
'6ff843ba685842aa82031d3f53c48b66326df7639a63d128974c5c14f31a0f33343a8c65551134ed1ae0f2b0dd2bb495dc81039e3eeb0aa1bb0388bbeac29183'
You can call :meth:`hash.update` as many times as you need to iteratively
update the hash:
>>> from hashlib import blake2b
>>> items = [b'Hello', b' ', b'world']
>>> h = blake2b()
>>> for item in items:
... h.update(item)
>>> h.hexdigest()
'6ff843ba685842aa82031d3f53c48b66326df7639a63d128974c5c14f31a0f33343a8c65551134ed1ae0f2b0dd2bb495dc81039e3eeb0aa1bb0388bbeac29183'
Using different digest sizes
----------------------------
BLAKE2 has configurable size of digests up to 64 bytes for BLAKE2b and up to 32
bytes for BLAKE2s. For example, to replace SHA-1 with BLAKE2b without changing
the size of output, we can tell BLAKE2b to produce 20-byte digests:
>>> from hashlib import blake2b
>>> h = blake2b(digest_size=20)
>>> h.update(b'Replacing SHA1 with the more secure function')
>>> h.hexdigest()
'd24f26cf8de66472d58d4e1b1774b4c9158b1f4c'
>>> h.digest_size
20
>>> len(h.digest())
20
Hash objects with different digest sizes have completely different outputs
(shorter hashes are *not* prefixes of longer hashes); BLAKE2b and BLAKE2s
produce different outputs even if the output length is the same:
>>> from hashlib import blake2b, blake2s
>>> blake2b(digest_size=10).hexdigest()
'6fa1d8fcfd719046d762'
>>> blake2b(digest_size=11).hexdigest()
'eb6ec15daf9546254f0809'
>>> blake2s(digest_size=10).hexdigest()
'1bf21a98c78a1c376ae9'
>>> blake2s(digest_size=11).hexdigest()
'567004bf96e4a25773ebf4'
Keyed hashing
-------------
Keyed hashing can be used for authentication as a faster and simpler
replacement for `Hash-based message authentication code
<http://en.wikipedia.org/wiki/Hash-based_message_authentication_code>`_ (HMAC).
BLAKE2 can be securely used in prefix-MAC mode thanks to the
indifferentiability property inherited from BLAKE.
This example shows how to get a (hex-encoded) 128-bit authentication code for
message ``b'message data'`` with key ``b'pseudorandom key'``:
>>> from hashlib import blake2b
>>> h = blake2b(key=b'pseudorandom key', digest_size=16)
>>> h.update(b'message data')
>>> h.hexdigest()
'3d363ff7401e02026f4a4687d4863ced'
As a practical example, a web application can symmetrically sign cookies sent
to users and later verify them to make sure they weren't tampered with:
>>> from hashlib import blake2b
>>> from hmac import compare_digest
>>>
>>> SECRET_KEY = b'pseudorandomly generated server secret key'
>>> AUTH_SIZE = 16
>>>
>>> def sign(cookie):
... h = blake2b(data=cookie, digest_size=AUTH_SIZE, key=SECRET_KEY)
... return h.hexdigest()
>>>
>>> cookie = b'user:vatrogasac'
>>> sig = sign(cookie)
>>> print("{0},{1}".format(cookie.decode('utf-8'), sig))
user:vatrogasac,349cf904533767ed2d755279a8df84d0
>>> compare_digest(cookie, sig)
True
>>> compare_digest(b'user:policajac', sig)
False
>>> compare_digesty(cookie, '0102030405060708090a0b0c0d0e0f00')
False
Even though there's a native keyed hashing mode, BLAKE2 can, of course, be used
in HMAC construction with :mod:`hmac` module:
>>> import hmac, hashlib
>>> m = hmac.new(b'secret key', digestmod=hashlib.blake2s)
>>> m.update(b'message')
>>> m.hexdigest()
'e3c8102868d28b5ff85fc35dda07329970d1a01e273c37481326fe0c861c8142'
Randomized hashing
------------------
By setting *salt* parameter users can introduce randomization to the hash
function. Randomized hashing is useful for protecting against collision attacks
on the hash function used in digital signatures.
Randomized hashing is designed for situations where one party, the message
preparer, generates all or part of a message to be signed by a second
party, the message signer. If the message preparer is able to find
cryptographic hash function collisions (i.e., two messages producing the
same hash value), then she might prepare meaningful versions of the message
that would produce the same hash value and digital signature, but with
different results (e.g., transferring $1,000,000 to an account, rather than
$10). Cryptographic hash functions have been designed with collision
resistance as a major goal, but the current concentration on attacking
cryptographic hash functions may result in a given cryptographic hash
function providing less collision resistance than expected. Randomized
hashing offers the signer additional protection by reducing the likelihood
that a preparer can generate two or more messages that ultimately yield the
same hash value during the digital signature generation process even if
it is practical to find collisions for the hash function. However, the use
of randomized hashing may reduce the amount of security provided by a
digital signature when all portions of the message are prepared
by the signer.
(`NIST SP-800-106 "Randomized Hashing for Digital Signatures"
<http://csrc.nist.gov/publications/nistpubs/800-106/NIST-SP-800-106.pdf>`_)
In BLAKE2 the salt is processed as a one-time input to the hash function during
initialization, rather than as an input to each compression function.
.. warning::
*Salted hashing* (or just hashing) with BLAKE2 or any other general-purpose
cryptographic hash function, such as SHA-256, is not suitable for hashing
passwords. See `BLAKE2 FAQ <https://blake2.net/#qa>`_ for more
information.
..
>>> import os
>>> from hashlib import blake2b
>>> msg = b'some message'
>>> # Calculate the first hash with a random salt.
>>> salt1 = os.urandom(blake2b.SALT_SIZE)
>>> h1 = blake2b(salt=salt1)
>>> h1.update(msg)
>>> # Calculate the second hash with a different random salt.
>>> salt2 = os.urandom(blake2b.SALT_SIZE)
>>> h2 = blake2b(salt=salt2)
>>> h2.update(msg)
>>> # The digests are different.
>>> h1.digest() != h2.digest()
True
Personalization
---------------
Sometimes it is useful to force hash function to produce different digests for
the same input for different purposes. Quoting the authors of the Skein hash
function:
We recommend that all application designers seriously consider doing this;
we have seen many protocols where a hash that is computed in one part of
the protocol can be used in an entirely different part because two hash
computations were done on similar or related data, and the attacker can
force the application to make the hash inputs the same. Personalizing each
hash function used in the protocol summarily stops this type of attack.
(`The Skein Hash Function Family
<http://www.skein-hash.info/sites/default/files/skein1.3.pdf>`_,
p. 21)
BLAKE2 can be personalized by passing bytes to the *person* argument:
>>> from hashlib import blake2b
>>> FILES_HASH_PERSON = b'MyApp Files Hash'
>>> BLOCK_HASH_PERSON = b'MyApp Block Hash'
>>> h = blake2b(digest_size=32, person=FILES_HASH_PERSON)
>>> h.update(b'the same content')
>>> h.hexdigest()
'20d9cd024d4fb086aae819a1432dd2466de12947831b75c5a30cf2676095d3b4'
>>> h = blake2b(digest_size=32, person=BLOCK_HASH_PERSON)
>>> h.update(b'the same content')
>>> h.hexdigest()
'cf68fb5761b9c44e7878bfb2c4c9aea52264a80b75005e65619778de59f383a3'
Personalization together with the keyed mode can also be used to derive different
keys from a single one.
>>> from hashlib import blake2s
>>> from base64 import b64decode, b64encode
>>> orig_key = b64decode(b'Rm5EPJai72qcK3RGBpW3vPNfZy5OZothY+kHY6h21KM=')
>>> enc_key = blake2s(key=orig_key, person=b'kEncrypt').digest()
>>> mac_key = blake2s(key=orig_key, person=b'kMAC').digest()
>>> print(b64encode(enc_key).decode('utf-8'))
rbPb15S/Z9t+agffno5wuhB77VbRi6F9Iv2qIxU7WHw=
>>> print(b64encode(mac_key).decode('utf-8'))

Tree mode
---------
Here's an example of hashing a minimal tree with two leaf nodes::
10
/ \
00 01
The example uses 64-byte internal digests, and returns the 32-byte final
digest.
>>> from hashlib import blake2b
>>>
>>> FANOUT = 2
>>> DEPTH = 2
>>> LEAF_SIZE = 4096
>>> INNER_SIZE = 64
>>>
>>> buf = bytearray(6000)
>>>
>>> # Left leaf
... h00 = blake2b(buf[0:LEAF_SIZE], fanout=FANOUT, depth=DEPTH,
... leaf_size=LEAF_SIZE, inner_size=INNER_SIZE,
... node_offset=0, node_depth=0, last_node=False)
>>> # Right leaf
... h01 = blake2b(buf[LEAF_SIZE:], fanout=FANOUT, depth=DEPTH,
... leaf_size=LEAF_SIZE, inner_size=INNER_SIZE,
... node_offset=1, node_depth=0, last_node=True)
>>> # Root node
... h10 = blake2b(digest_size=32, fanout=FANOUT, depth=DEPTH,
... leaf_size=LEAF_SIZE, inner_size=INNER_SIZE,
... node_offset=0, node_depth=1, last_node=True)
>>> h10.update(h00.digest())
>>> h10.update(h01.digest())
>>> h10.hexdigest()
