- Drop support for Python 3.6 (#209) and declare support for 3.11 (#208).
- Upgrade
pytest
dependency to fix a security issue. - Upgrade
pytest-cov
as well, for good measure. - Upgrade MyPy (#211).
- Remove debug logging from
rsa/key.py
(#194). - Remove overlapping slots in
PrivateKey
andPublicKey
. (#189). - Do not include CHANGELOG/LICENSE/README.md in wheel (#191).
- Fixed Key Generation Unittest: Public and Private keys are assigned the wrong way around (#188).
- Switch to Poetry for dependency and release management.
- Compatibility with Python 3.10.
- Chain exceptions using
raise new_exception from old_exception
(#157) - Added marker file for PEP 561. This will allow type checking tools in dependent projects to use type annotations from Python-RSA (#136).
- Use the Chinese Remainder Theorem when decrypting with a private key. This makes decryption 2-4x faster (#163).
- Fix picking/unpickling issue introduced in 4.7 (#173)
- Fix threading issue introduced in 4.7 (#173)
- Fix #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)
- Reuse of blinding factors to speed up blinding operations. Fixes #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
- 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.
- 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.
- Fix #129 Installing from source gives UnicodeDecodeError.
- Switched to using Poetry 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. Thanks Adelapie for pointing this out.
- Removed deprecated modules:
- rsa.varblock
- rsa.bigfile
- rsa._version133
- rsa._version200
- Removed CLI commands that use the VARBLOCK/bigfile format.
- Ensured that PublicKey.save_pkcs1() and PrivateKey.save_pkcs1() always return bytes.
- Dropped support for Python 2.6 and 3.3.
- Dropped support for Psyco.
- Miller-Rabin iterations determined by bitsize of key. #58
- Added function
rsa.find_signature_hash()
to return the name of the hashing algorithm used to sign a message.rsa.verify()
now also returns that name, instead of always returningTrue
. #78 - Add support for SHA-224 for PKCS1 signatures. #104
- Transitioned from
requirements.txt
to Pipenv for package management.
- Fixed dates in CHANGELOG.txt
- Included tests/private.pem in MANIFEST.in
- Included README.md and CHANGELOG.txt in MANIFEST.in
- Moved development to GitHub: https://github.com/sybrenstuvel/python-rsa
- Solved side-channel vulnerability by implementing blinding, fixes #19
- Deprecated the VARBLOCK format and rsa.bigfile module due to security issues, see #13
- Integration with Travis-CI [1], Coveralls [2] and Code Climate [3]
- Deprecated the old rsa._version133 and rsa._version200 submodules, they will be completely removed in version 4.0.
- Add an 'exponent' argument to key.newkeys()
- Switched from Solovay-Strassen to Miller-Rabin primality testing, to comply with NIST FIPS 186-4 [4] as probabilistic primality test (Appendix C, subsection C.3):
- Fixed bugs #12, #14, #27, #30, #49

- Thanks to Filippo Valsorda: Fix BB'06 attack in verify() by switching from parsing to comparison. See [1] for more information.
- Simplified Tox configuration and dropped Python 3.2 support. The coverage package uses a u'' prefix, which was reintroduced in 3.3 for ease of porting.

- Added character encoding markers for Python 2.x
- Added per-file licenses
- Added support for wheel packages
- Made example code more consistent and up to date with Python 3.4
- Mentioned support for Python 3 in setup.py
- Fixed some bugs
- Dropped support for Python 2.5
- Added Python 3.3 to the test environment.
- Removed dependency on Distribute
- Added support for loading public keys from OpenSSL
- Fixed doctests for Python 2.7
- Removed obsolete unittest so all tests run fine on Python 3.2
- Big, big credits to Yesudeep Mangalapilly for all the changes listed below!
- Added ability to generate keys on multiple cores simultaneously.
- Massive speedup
- Partial Python 3.2 compatibility (core functionality works, but saving or loading keys doesn't, for that the pyasn1 package needs to be ported to Python 3 first)
- Lots of bug fixes
- Removed unused import of abc module
- Changed the meaning of the keysize to mean the size of
n
rather than the size of bothp
andq
. This is the common interpretation of RSA keysize. To get the old behaviour, double the keysize when generating a new key. - Added a lot of doctests
- Added random-padded encryption and decryption using PKCS#1 version 1.5
- Added hash-based signatures and verification using PKCS#1v1.5
- Modeling private and public key as real objects rather than dicts.
- Support for saving and loading keys as PEM and DER files.
- Ability to extract a public key from a private key (PEM+DER)
- Security improvements by Barry Mead.
