build(deps): bump cryptography from 2.8 to 3.1.1

[dependabot-preview]

Bumps cryptography from 2.8 to 3.1.1.

Changelog

Sourced from cryptography's changelog.

3.1.1 - 2020-09-22

• Updated Windows, macOS, and manylinux wheels to be compiled with OpenSSL 1.1.1h.

3.1 - 2020-08-26

• BACKWARDS INCOMPATIBLE: Removed support for idna based U-label parsing in various X.509 classes. This support was originally deprecated in version 2.1 and moved to an extra in 2.5.
• Deprecated OpenSSL 1.0.2 support. OpenSSL 1.0.2 is no longer supported by the OpenSSL project. The next version of cryptography will drop support for it.
• Deprecated support for Python 3.5. This version sees very little use and will be removed in the next release.
• backend arguments to functions are no longer required and the default backend will automatically be selected if no backend is provided.
• Added initial support for parsing certificates from PKCS7 files with ~cryptography.hazmat.primitives.serialization.pkcs7.load_pem_pkcs7_certificates and ~cryptography.hazmat.primitives.serialization.pkcs7.load_der_pkcs7_certificates .
• Calling update or update_into on ~cryptography.hazmat.primitives.ciphers.CipherContext with data longer than 2^31^ bytes no longer raises an OverflowError. This also resolves the same issue in /fernet.

3.0 - 2020-07-20

• BACKWARDS INCOMPATIBLE: Removed support for passing an ~cryptography.x509.Extension instance to ~cryptography.x509.AuthorityKeyIdentifier.from_issuer_subject_key_identifier, as per our deprecation policy.

• BACKWARDS INCOMPATIBLE: Support for LibreSSL 2.7.x, 2.8.x, and 2.9.0 has been removed (2.9.1+ is still supported).

• BACKWARDS INCOMPATIBLE: Dropped support for macOS 10.9, macOS users must upgrade to 10.10 or newer.

• BACKWARDS INCOMPATIBLE: RSA ~cryptography.hazmat.primitives.asymmetric.rsa.generate_private_key no longer accepts public_exponent values except 65537 and 3 (the latter for legacy purposes).

• BACKWARDS INCOMPATIBLE: X.509 certificate parsing now enforces that the version field contains a valid value, rather than deferring this check until ~cryptography.x509.Certificate.version is accessed.

• Deprecated support for Python 2. At the time there is no time table for actually dropping support, however we strongly encourage all users to upgrade their Python, as Python 2 no longer receives support from the Python core team.

  If you have trouble suppressing this warning in tests view the FAQ entry addressing this issue <faq-howto-handle-deprecation-warning>.

• Added support for OpenSSH serialization format for ec, ed25519, rsa and dsa private keys: ~cryptography.hazmat.primitives.serialization.load_ssh_private_key for loading and ~cryptography.hazmat.primitives.serialization.PrivateFormat.OpenSSH for writing.

• Added support for OpenSSH certificates to ~cryptography.hazmat.primitives.serialization.load_ssh_public_key.

• Added ~cryptography.fernet.Fernet.encrypt_at_time and ~cryptography.fernet.Fernet.decrypt_at_time to ~cryptography.fernet.Fernet.

• Added support for the ~cryptography.x509.SubjectInformationAccess X.509 extension.

• Added support for parsing ~cryptography.x509.SignedCertificateTimestamps in OCSP responses.

• Added support for parsing attributes in certificate signing requests via ~cryptography.x509.CertificateSigningRequest.get_attribute_for_oid.

• Added support for encoding attributes in certificate signing requests via ~cryptography.x509.CertificateSigningRequestBuilder.add_attribute.

• On OpenSSL 1.1.1d and higher cryptography now uses OpenSSL's built-in CSPRNG instead of its own OS random engine because these versions of OpenSSL properly reseed on fork.

• Added initial support for creating PKCS12 files with ~cryptography.hazmat.primitives.serialization.pkcs12.serialize_key_and_certificates.

2.9.2 - 2020-04-22

• Updated the macOS wheel to fix an issue where it would not run on macOS versions older than 10.15.

2.9.1 - 2020-04-21

• Updated Windows, macOS, and manylinux wheels to be compiled with OpenSSL 1.1.1g.

2.9 - 2020-04-02
