Clean up stdout when using unittest test runner

2021-02-24T12:35:18+00:00

While pytest is the preferred test runner via tox, it looks like some folks are
still running tests via `python3 setup.py test` which uses unittest and does
not have good support for capturing stdout. To make using unittest slightly
more friendly,  we further swallow stdout / stderr for cli tests, and ensure
print statements start on a newline.

Fix #164: Add padding length check as described by PKCS#1 v1.5

2020-11-15T14:50:01+00:00

According to PKCS#1 v1.5, the padding should be at least 8 bytes long.
See https://tools.ietf.org/html/rfc8017#section-7.2.2 step 3 for more info.

Limit SHA3 support to Python 3.6+

2020-06-11T18:22:30+00:00

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](https://github.com/sybrenstuvel/python-rsa/issues/147).

Fix CVE-2020-13757: detect cyphertext modifications by prepending zero bytes

2020-06-03T12:57:17+00:00

Reject cyphertexts that have been modified by prepending zero bytes, by
checking the cyphertext length against the expected size (given the
decryption key). This resolves CVE-2020-13757.

The same approach is used when verifying a signature.

Thanks Carnil for pointing this out on https://github.com/sybrenstuvel/python-rsa/issues/146

Drop character encoding markers for Python 2.x

Add support for SHA3 hashing

2019-08-04T15:47:26+00:00

This is based on https://github.com/sybrenstuvel/python-rsa/pull/96, with
a few improvements:
  - The minimum of one use of SHA3 in a unit test, to at least touch it at
    some point.
  - Documented the support of SHA3.
  - Only install the third-party library required by Python 3.5 when we're
    running on Python 3.5. Newer Python versions support SHA3 natively.

Removed compatibility code for Python 2.7 and 3.4

2019-08-04T15:05:58+00:00

Changed unittest to cover the new SHA-224 hash method

2018-02-05T12:59:52+00:00

Support signing a pre-calculated hash (#87)

2017-05-07T09:39:47+00:00

* Split the hashing out of the sign method

This code change adds support to split the hashing of a message
and the actual signing of the message.

* Updating unit test and documentation

This commit updates the unit test and usage docs. In addition,
This change removes a redundant error check inside rsa.sign().

* Refactore unit tests and code comments

Removed the print statements from the unit test and refactored a
few code comments to improve readability.

* Rename hash function

The new hash function had the same name as a function in the
standard library. This commit changes the name to avoid conflicts.

* Rename hash function to compute_hash()

This commit renames the hash function to compute_hash().
