Bitcoinproof creates a forgery-proof timestamp for your data, secured by the Bitcoin network. It allows you to prove that a certain event happened before a certain point in time. Maybe you want to prove that the damage in your flat already existed when you moved in, or that you were in possession of a great artwork before it was published, proving you are the author.
clens is a convenience library that aids in porting code from OpenBSD to different operating systems. Operating systems traditionally have different enough APIs that porting code is painful and can litter pretty code with ugly #ifdefs. In order to keep code readable and drastically reduce the number of #ifdefs needed, clens brings other APIs or missing functions into specific OS "focus".
minidb is a Python module that utilizes the SQLite3 database library in order to store and retrieve Python objects. It utilizes Python's __slots__ mechanism to determine the column names, and uses the class name for table names. Data is always stored as text in the database, but will be converted using the type specified in __slots__ (which therefore has to be a dict).
