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 & 4.6 - released 2020-06-12
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 & 4.5 - released 2020-06-12
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.
