DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html

Crypto++ is a free C++ class library of cryptographic schemes originally written by Wei Dai. The library is now maintained by a community of volunteers. The Crypto++ website is located at https://cryptopp.com/, and the source code is located at https://github.com/weidai11/cryptopp. The repository was moved in response to developer requests for Git access. The SourceForge site will remain in "read only" mode for historical purposes. You should visit the Crypto++ website at https://cryptopp.com/ or GitHub at https://github.com/weidai11/cryptopp to view the latest news, download the latest source code, file bugs and request features. We thank SourceForge for hosting us through the years.
