Update cryptography to 2.5

[pyup-bot]

This PR updates cryptography from 2.4.2 to 2.5.

Changelog

2.5

~~~~~~~~~~~~~~~~

* **BACKWARDS INCOMPATIBLE:** :term:`U-label` strings were deprecated in
version 2.1, but this version removes the default ``idna`` dependency as
well. If you still need this deprecated path please install cryptography
with the ``idna`` extra: ``pip install cryptography[idna]``.
* **BACKWARDS INCOMPATIBLE:** The minimum supported PyPy version is now 5.4.
* Numerous classes and functions have been updated to allow :term:`bytes-like`
types for keying material and passwords, including symmetric algorithms, AEAD
ciphers, KDFs, loading asymmetric keys, and one time password classes.
* Updated Windows, macOS, and ``manylinux1`` wheels to be compiled with
OpenSSL 1.1.1a.
* Added support for :class:`~cryptography.hazmat.primitives.hashes.SHA512_224`
and :class:`~cryptography.hazmat.primitives.hashes.SHA512_256` when using
OpenSSL 1.1.1.
* Added support for :class:`~cryptography.hazmat.primitives.hashes.SHA3_224`,
:class:`~cryptography.hazmat.primitives.hashes.SHA3_256`,
:class:`~cryptography.hazmat.primitives.hashes.SHA3_384`, and
:class:`~cryptography.hazmat.primitives.hashes.SHA3_512` when using OpenSSL
1.1.1.
* Added support for :doc:`/hazmat/primitives/asymmetric/x448` when using
OpenSSL 1.1.1.
* Added support for :class:`~cryptography.hazmat.primitives.hashes.SHAKE128`
and :class:`~cryptography.hazmat.primitives.hashes.SHAKE256` when using
OpenSSL 1.1.1.
* Added initial support for parsing PKCS12 files with
:func:`~cryptography.hazmat.primitives.serialization.pkcs12.load_key_and_certificates`.
* Added support for :class:`~cryptography.x509.IssuingDistributionPoint`.
* Added ``rfc4514_string()`` method to
:meth:`x509.Name <cryptography.x509.Name.rfc4514_string>`,
:meth:`x509.RelativeDistinguishedName
<cryptography.x509.RelativeDistinguishedName.rfc4514_string>`, and
:meth:`x509.NameAttribute <cryptography.x509.NameAttribute.rfc4514_string>`
to format the name or component an :rfc:`4514` Distinguished Name string.
* Added
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.from_encoded_point`,
which immediately checks if the point is on the curve and supports compressed
points. Deprecated the previous method
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicNumbers.from_encoded_point`.
* Added :attr:`~cryptography.x509.ocsp.OCSPResponse.signature_hash_algorithm`
to ``OCSPResponse``.
* Updated :doc:`/hazmat/primitives/asymmetric/x25519` support to allow
additional serialization methods. Calling
:meth:`~cryptography.hazmat.primitives.asymmetric.x25519.X25519PublicKey.public_bytes`
with no arguments has been deprecated.
* Added support for encoding compressed and uncompressed points via
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.public_bytes`. Deprecated the previous method
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicNumbers.encode_point`.
