Python wrapper around a small subset of the OpenSSL library. Includes: X509 Certificates, SSL Context objects, SSL Connection objects using Python sockets as transport layer.

sshproxy is a pure python implementation of an ssh authenticating proxy. It allows users to connect to remote sites without having to know the password or key of the remote sites. ACL rules can ... [More] be set up to allow or deny users based on different parameters like their IP address or the time of the day. Access attempts are logged via syslog, and an enhanced "action log" system is under development. The client is the standard ssh client. [Less]

The Virtual Ideal Functionality Framework (VIFF) is a framework for creating efficient and secure multi-party computations (SMPC). Players, who do not trust each other, participate in a joint ... [More] computation based on their private inputs. The computation is done using a cryptographic protocol which allows them to obtain a correct answer without revealing their inputs. Operations supported include addition, multiplication, and comparison, all with Shamir secret shared outputs. [Less]

PyGPGME is a Python module that lets you sign, verify, encrypt and decrypt messages using the OpenPGP format. It is built on top of the GNU Privacy Guard and the GPGME library.

The Mandos system allows computers to have encrypted root file systems and at the same time be capable of remote and/or unattended reboots. The computers run a small client program in the initial ... [More] RAM disk environment which will communicate with a server over a network. All network communication is encrypted using TLS. The clients are identified by the server using an OpenPGP key; each client has one unique to it. The server sends the clients an encrypted password. The encrypted password is decrypted by the clients using the same OpenPGP key, and the password is then used to unlock the root file system, whereupon the computers can continue booting normally.

A collection of ad-hoc simple tools and script to play with home-made cryptographic systems.

Cache timing attack research for masters. Focuses mainly on AES for dm-crypt, jails, sanboxes, and openssl. Main Webpage: http://www.cs.rit.edu/~bdi8241/masters.php --- Brad Israel http://www.cs.rit.edu/~bdi8241/

Demos from the Paramiko Python Extension reworked to use the standard VyperLogix Library. The VyperLogix Library now has support for SFTP that requires very little code for the developer who wishes to use all this power.

This library is a pure python cryptographic library for OpenSSL It provides: Hashing Algorithms: MD5, SHA1, SHA224, SHA256, SHA384, SHA512 Secret Key Encryption: DES, DES-EDE3, BF, AES-128 ... [More] , AES-192, AES-256 Confidentiality Modes: CBC, CFB, OFB, ECB OpenSSL Pseudo Random number generation. Future work would include Public Key Encryption: RSA (encrypt/decrypt, sign/verify) Certificates: X.509 Certificate parsing and validation Protocols: (TLS and SSL) [Less]
