Name: python-pprp
Version: 0.2.7
Release: 1
Summary: A pure-Python Rijndael (AES) and PBKDF2 library. Python 2.7 and Python3 compatible.
License: GPL 2
URL: https://github.com/dsoprea/RijndaelPbkdf
Source0: https://mirrors.aliyun.com/pypi/web/packages/7d/8a/6bcc32e0f6cf0a9e0132230cb41652bd3df3dbdb0e673e31b720b6111deb/pprp-0.2.7.tar.gz
BuildArch: noarch
%description
[](https://travis-ci.org/dsoprea/RijndaelPbkdf)
## Overview
This package was a remedy to there being no PyPI-published, pure-Python
Rijndael (AES) implementations, and that nothing available, in general, was
compatible with both Python2 *and* Python3. The same is true of the PBKDF2
key-expansion algorithm.
The encryptor takes a source generator (which yields individual blocks). There
are source-generators provided for both data from a variable and data from a
file. It is trivial if you'd like to write your own. The encryptor and
decryptor functions are written as generators. Decrypted data has PKCS7
padding. A utility function is provided to trim this (*trim_pkcs7_padding*).
The implementation includes Python2 and Python3 implementations of both
Rijndael and PBKDF2, and chooses the version when loaded.
The default block-size is 128-bits in order to be compatible with AES.
This project is also referred to as *pprp*, which stands for "Pure Python
Rijndael and PBKDF2".
## Installation
Install via *pip*:
```
$ sudo pip install pprp
```
## Example
Encrypt and decrypt the data, and compare the results. This was copied directly
from the unit-test.
```python
passphrase = 'password'.encode('ASCII')
salt = 'salt'.encode('ASCII')
key_size = 32
data = "this is a test" * 100
data_bytes = data.encode('ASCII')
key = pprp.pbkdf2(passphrase, salt, key_size)
# Create a source from available data.
sg = pprp.data_source_gen(data_bytes)
# Feed the source into the encryptor.
eg = pprp.rijndael_encrypt_gen(key, sg)
# Feed the encryptor into the decryptor.
dg = pprp.rijndael_decrypt_gen(key, eg)
# Sink the output into an IO-stream.
decrypted = pprp.decrypt_sink(dg)
# self.assertEquals(data_bytes, decrypted)
```
## Notes
The generators can take a block-size in the event that you don't want the
default. The default block-size can also be changed via the PPRP_BLOCK_SIZE
environment variable.
