A word of warning to those considering using this. While I completely understand why people might want to encrypt/decrypt files within their public Git repositories, doing so doesn't come for free.

As Junio C Hamano explains more eloquently and in greater depth here[1], one thing to bear in mind with this (and similar) tools is that they store the managed files as binary blobs, regardless of their original format, meaning that a change to the source file of even a single bit will result in an entirely different uncompressed blob being stored, rather than a compressible textual delta.
