  • Hardware requirements
    i386 or higher Linux box (not tested on other platforms).
    About 200 KBytes of free disk space to install BestCrypt software.
    Disk space for containers is not limited.

  • Software requirements
    Linux system with kernel version 2.2.0-2.3.36, 2.4.3 or higher. Kernel configuration MUST allow loadable modules support (see Kernel HOW TO or Modules mini-HOW TO).
    BestCrypt for Linux is distributed in sources only, so you will need Linux kernel development environment ("Kernel development" category in RedHat distributions):
    • Kernel developLinux kernel sources (the same version as you are running)
    • GNU C/C++ compiler recommended for kernel compilation (2.2.x kernels use gcc 2.7.2, 2.4.x kernels use gcc 2.91

  • Containers considerations
    • Filename format notes
      Different filesystems have different filename restrictions. When copying file from one filesystem to another these restrictions should be kept in mind. Most frustrating limitation is FAT filesystem file naming scheme "8.3" - only 8 characters for name and 3 characters for file extension. If you will copy files with longer names to container formatted with FAT, file names will be truncated to "8.3" format.
    • Filesystem accessibility
      BestCrypt containers can be created and read under various operating systems and can be formatted with various filesystems. Following table provides filesystem accessibility matrix for BestCrypt containers.
      See also Filesystems-HOWTO.

      (*) Note: BestCrypt for Linux uses container format incompatible with BestCrypt for DOS/Windows 3.11 containers. In order to convert containers BestCrypt for Windows 95 or later should be used.
    • Container size (file size limitations)
      Container size limitations are implied by file size limitations of filesystem where container resides. Newer +Linux distributions (RedHat 7.0+, SuSE 7.0+, Debian 3.0+) include so-called Large File Support which extends conventional 2GB Linux file limit.
      See also Large File Support in Linux page.
