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 is available at http://simplecrypto.readthedocs.org.
The full source code repository is at https://github.com/boppreh/simplecrypto.
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. If you wish to compile it I suggest using the Mingw tools as indicated here.
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=='
Add HMAC support.
Use SHA256 as default RSA hash
Allow selection of PRNG used for RSA key generation
Minor changes for better Python2 support
Add project to Travis and Coverall.
Increase test coverage to 100%.
Add installation instructions.
Rename guess_hash to guess_transformation.
Add serialize to RSA keys.
Allow RSA keys to receive PEM encoded keys in the constructor.
Implement __repr__ method in base Key class (you can now print keys).
Split package into modules key, formats, hashes, random and exceptions.
Update project information (keywords, classifiers, description, etc).
Add send and receive functions for secure message building.
Raise EncryptionError instead of generic errors.
Slightly better test coverage.
Add base Key class.
Introduce raw versions of encrypt and decrypt.
Implemented key printing and comparison.
Return str from to_base64 and allow from_base64 to receive str.
Create classes for different key types.
Change return from to_hex to str for consistency with base64.
guess_hash function moved to different module.
Automatically use session keys when encrypting large messages.
