wxSFTP aims to be a simple, easy-to-use, and portable SFTP client. "Simple" means that the program will have only the main features needed. The structure consists of a two panel window, one for the local filesystem and another for the remote filesystem. To be easy to use the program is a graphical client that will be HIG compliant.
The WiKID Strong Authentication System is a highly scalable, secure two-factor authentication system. It is simple to implement and maintain, allows users to be validated automatically, requires no hardware tokens, has a simple API for application support (via Ruby, PHP, Java, COM, Python, etc.), supports multiple domains, and supports replication for fault tolerance and scalability. It also supports mutual /host and transaction authentication, wireless tokens only domains, locked tokens (to your PC), anti-keystroke logger keypad PIN entry, etc.
OneTime is a command-line encryption program that uses the one-time pad algorithm to allow two parties to communicate securely, without worrying about unauthorized people listening in. It compresses plaintext input to save pad, has features that assist with the bureaucracy of pad management, and comes with built-in help.
PyKCS11 is a PKCS#11 wrapper for Python. It lets you access almost all PKCS#11 functions and data types using any PKCS#11 library, such as the various modules supplied by smartcard vendors. It comes with two interfaces: a low level and very thin interface over the original PKCS#11 API, generated using the SWIG compiler (designed for library tests), and a high level interface that offers simpler access (with few limits) to the PKCS#11 APIs.
finic helps users manage their finances. It can be used on a local network (as a client-server system for many users) or on local computer (client only for one user), with separation of accounts, clauses, and customers. It can encrypt information and manage different users with different access rights. Reports can be generated as HTML, PDF, or XLS files or through an internal print preview system. An API is available for creating extensions.
Keyczar is a cryptographic toolkit designed to make it easier and safer for developers to use cryptography in their applications. It supports authentication and encryption with both symmetric and asymmetric keys. Cryptography is easy to get wrong. Developers can choose improper cipher modes, use obsolete algorithms, compose primitives in an unsafe manner, or fail to anticipate the need for key rotation. Keyczar abstracts some of these details by choosing safe defaults, automatically tagging outputs with key version information, and providing a simple programming interface.
Open Transactions is a solid, easy-to-use, financial crypto and digital cash library, including an API, server, and test client. It features anonymous numbered accounts, untraceable digital cash, triple-signed receipts, basket currencies, and signed XML contracts. It also supports cheques, invoices, payment plans, markets with trades, and other instruments. It uses OpenSSL and Lucre blinded tokens.
Shasplit takes a large data block, splits it into smaller parts, and puts those parts into an SHA-based content-addressed store. Reassembling those parts is a trivial "cat" invocation. Repeating parts (e.g., from previous split operations) are stored only once, which allows efficient incremental backups of whole LVM snapshots via Rsync. Shasplit shows its strengths on encrypted block devices, but might be useful for non-encrypted data, too.
