Description

Generate a lot of random junk.

• huge files
• random character stream
• specific character sequence

Example uses - generate:

• specific number of characters for testing web forms
• restricted range character stream
• control characters, 'high characters', emojis for fuzzing application input
• specific byte sequence
• Unicode character range
• file overwrites to the exact byte count
• custom text strings as content filler
• long password strings

• specific file size (e.g. 777 bytes, 10 MB, 2 GB)
• huge files (x64 version: 4GB+ files)
• fast generation rates on x64 version: ~1.25GB/sec by modest CPUs on Linux
• files for zipping / hashing / integrity / transfer / speed tests.

RND.zip contains the source code and the x86/x64 executables for Linux, Windows, Raspberry Pi.
