python3-rsa: Update to version 4.8 and python-3.10
- Update from 4.0 to 4.8 - Update of rootfile - Changelog - Switch to [Poetry](https://python-poetry.org/) for dependency and release management. - Compatibility with Python 3.10. - Chain exceptions using `raise new_exception from old_exception` ([#157](sybrenstuvel/python-rsa#157)) - Added marker file for PEP 561. This will allow type checking tools in dependent projects to use type annotations from Python-RSA ([#136](sybrenstuvel/python-rsa#136)). - Use the Chinese Remainder Theorem when decrypting with a private key. This makes decryption 2-4x faster ([#163](sybrenstuvel/python-rsa#163)). - Fix picking/unpickling issue introduced in 4.7 ([#173](sybrenstuvel/python-rsa#173)) - Fix threading issue introduced in 4.7 ([#173](sybrenstuvel/python-rsa#173)) - Fix [#165](sybrenstuvel/python-rsa#165): CVE-2020-25658 - Bleichenbacher-style timing oracle in PKCS#1 v1.5 decryption code - Add padding length check as described by PKCS#1 v1.5 (Fixes [#164](sybrenstuvel/python-rsa#164)) - Reuse of blinding factors to speed up blinding operations. Fixes [#162](sybrenstuvel/python-rsa#162). - Declare & test support for Python 3.9 Version 4.4 and 4.6 are almost a re-tagged release of version 4.2. It requires Python 3.5+. To avoid older Python installations from trying to upgrade to RSA 4.4, this is now made explicit in the `python_requires` argument in `setup.py`. There was a mistake releasing 4.4 as "3.5+ only", which made it necessary to retag 4.4 as 4.6 as well. No functional changes compared to version 4.2. Version 4.3 and 4.5 are almost a re-tagged release of version 4.0. It is the last to support Python 2.7. This is now made explicit in the `python_requires` argument in `setup.py`. Python 3.4 is not supported by this release. There was a mistake releasing 4.4 as "3.5+ only", which made it necessary to retag 4.3 as 4.5 as well. Two security fixes have also been backported, so 4.3 = 4.0 + these two fixes. - Choose blinding factor relatively prime to N. Thanks Christian Heimes for pointing this out. - Reject cyphertexts (when decrypting) and signatures (when verifying) that have been modified by prepending zero bytes. This resolves CVE-2020-13757. Thanks Carnil for pointing this out. - Rolled back the switch to Poetry, and reverted back to using Pipenv + setup.py for dependency management. There apparently is an issue no-binary installs of packages build with Poetry. This fixes [#148](sybrenstuvel/python-rsa#148) - Limited SHA3 support to those Python versions (3.6+) that support it natively. The third-party library that adds support for this to Python 3.5 is a binary package, and thus breaks the pure-Python nature of Python-RSA. This should fix [#147](sybrenstuvel/python-rsa#147). - Added support for Python 3.8. - Dropped support for Python 2 and 3.4. - Added type annotations to the source code. This will make Python-RSA easier to use in your IDE, and allows better type checking. - Added static type checking via [MyPy](http://mypy-lang.org/). - Fix [#129](sybrenstuvel/python-rsa#129) Installing from source gives UnicodeDecodeError. - Switched to using [Poetry](https://poetry.eustace.io/) for package management. - Added support for SHA3 hashing: SHA3-256, SHA3-384, SHA3-512. This is natively supported by Python 3.6+ and supported via a third-party library on Python 3.5. - Choose blinding factor relatively prime to N. Thanks Christian Heimes for pointing this out. - Reject cyphertexts (when decrypting) and signatures (when verifying) that have been modified by prepending zero bytes. This resolves CVE-2020-13757.
