slm4j (Starschema License Manager for Java) is a simple and easy-to-use license file generator and validator package for Java programs. It includes a command line tool for generating private and public keys for cryptographic signing, and a runtime class (or jar module) to validate the generated keys. The signed data is an ASCII armored file, which could store date or time limitations, functionality restrictions, or any user specified strings. The embedded license file validation ensures that file is not modified by using the DSA algorithm.
pg_greentrunk provides fundamental components of GreenTrunk, an interface protocol (API) for using a PostgreSQL database with Python. It provides an interface for implementations to use, and provides documentation in the form of Python modules to allow immediate access to object descriptions, even when inside a Python console.
pg_pqueue is a Python package that provides low-level PQ protocol classes for interacting with a PostgreSQL database. It supports version 3.0 of the protocol. The package also provides a basic protocol transaction class. This class keeps the state of the protocol in an interrupt safe manner, and validates the integrity of the communication as messages are received. In general, you probably will never use this package directly, unless you are writing a driver.
py-bcrypt is a Python wrapper of OpenBSD's Blowfish password hashing code, as described in "A Future-Adaptable Password Scheme" by Niels Provos and David Mazières. This system hashes passwords using a version of Bruce Schneier's Blowfish block cipher with modifications designed to raise the cost of off-line password cracking and frustrate fast hardware implementation. The computation cost of the algorithm depends on a parameter, so it can be increased as computers get faster.
SQLiteDBMS is a database management server for SQLite. It allows an sqlite3 process to be accessed via a TCP/IP network. It provides Extended SQL, SSL, basic authentication, query caching, WebDAV, access control, and replication. It includes a simple Web server that takes HTTP requests and sends XML responses.
