zfec is a fast, portable, and programmable implementation of erasure coding. The project includes a C library, a Python library, and a command-line tool.

Erasure coding is also known as "forward error correction", which is the generation of redundant blocks of information such that if some blocks are lost then the original data can be recovered from the remaining blocks. The RAID-5 algorithm is an erasure code.

But instead of recovering from the loss of only a single element, zfec can be parameterized to choose in advance the number of elements whose loss it can tolerate.
