simplecrypto 0.3.2

Simple cryptographic library for hashing and encrypting

Cryptographic library with really simple API.

Includes functions for hashes, symmetric and asymmetric crypto, along with helper functions. Acts as a wrapper for PyCrypto and a few standard libraries.

Documentation

Documentation is available at http://simplecrypto.readthedocs.org.

The full source code repository is at https://github.com/boppreh/simplecrypto.

Installation

pip install simplecrypto

This library depends on PyCrypto. On Linux this is installed automatically by pip. If the dependency installation fail on Windows, you may want to use a prebuilt installer.

Usage

from simplecrypto import sha1, encrypt, decrypt, RsaKeypair, base64

sha1('The quick brown fox jumps over the lazy dog')
# '2fd4e1c67a2d28fced849ee1bb76e7391b93eb12'

# `encrypt` and `decrypt` use AES-256.
m = encrypt('secret message', 'secret key')
print(m)
# 'uRKa9xX7zW6QT1yJxIQb5E/0DzaxQglVggnFam5K'
decrypt(m, 'secret key')
# b'secret message'

skey = RsaKeypair(2048)
pkey = skey.publickey

m = pkey.encrypt('secret message')
skey.decrypt(m)
# b'secret message'

s = skey.sign('authenticated message')
pkey.verify('authenticated message', s)
# True

base64('message')
# 'bWVzc2FnZQ=='
