B1 is an open archive file format that supports data compression and archiving[ citation needed]. B1 files use the file extension ".b1" or ".B1" and the MIME media type application/x-b1. B1 incorporates the LZMA compression algorithm. [1] B1 archive combines a number of files and folders into one or more volumes, optionally adding compression and encryption. Construction of the B1 archive involves creating a binary stream of records and building volumes of that stream. The B1 archive format supports password-based AES-256 encryption. [2] B1 files are created and opened with its native open-source B1 Pack Tool, as well as B1 Free Archiver utility. [3] [4]
B1 Pack is an open-source software project that produces a cross-platform command-line tool and a Java library for creating and extracting file archives in the B1 archive format. Source code of the project is published at GitHub. [5] B1 Pack Project is released under the Apache License. [6] The B1 Pack Tool module builds a single executable JAR file which can create, list, and extract B1 archive files from a command-line interface. [7]
