rsbkb - CLI工具：编码器/解码器、CTF和反向工程

项目说明

rsbkb (Rust blackbag)

What is it?

rsbkb has multiple tools which are designed to be called directly (through
symlinks, like busybox). This allows operations on data to be chained
easily like CyberChef but through pipes.

It also includes practical tools like entropy, a binary grep, a
timestamp decoder, etc.

Quick start

1. install with cargo install rsbkb or download the binary from the releases page
2. run rsbkb to list applets
3. run rsbkb help <applet> to learn more
4. optionally create symlinks to call applets directly: rsbkb symlink

Examples

Read 10 bytes from /etc/passwd starting at offset 0x2f, then xor with
0xF2, encode it in URL-safe base64 and finally URL encode it:

examples:

How to use

Build it / Get it

* cargo build --release
* cargo install rsbkb
* get the binary from the releases page.
* get the latest artifact from the Actions page.

Usage

* Almost all tools take as an argument on the command line or if not present, read from stdin
* Tool name can be specified on the command line rsbkb TOOL
* Or can be called busybox-style: ln -s rsbkb unhex ; unhex 4142. Create symlinks with:

Included tools

* hex: hex encode
* unhex: decode hex data (either in the middle of arbitrary data, or strictly)
* b64: base64 encode (use -u or --URL for URL-safe b64)
* d64: base64 decode (use -u or --URL for URL-safe b64)
* urlenc: url encode (see --help for ad options)
* urldec: url decode
* xor: xor (use -x to specify the key, in hex, -f to specify a file)
* crc: all CRC algorithms implemented in the Crc crate
* crc16: CRC-16
* crc32: CRC-32
* bofpatt / boffpattoff: buffer o pattern generator / offset calculator
* tsdec: decode timestamps (Epoch with different resolutions, Windows FILETIME)
* slice: take a "slice" of a file (like dd):
* slice input_file 10 will output input_file from offset 10 on stdout
* slice input_file 0x10 0x20 will do the same from 0x10 to 0x20 (excluded)
* slice input_file 0x10 +0xFF will copy 0xFF bytes starting at 0x10
* slice input_file -0x10 will the last 0x10 bytes from input_file
* entropy: entropy of a file
* bgrep: simple binary grep
* findso: find which ELF shared library (.so) exports a given name/function
* inflate and deflate: raw inflate/deflate compression, fault tolerant and with optional Zlib header support
* base: easy radix con of big integers
* escape: backslash-escape special characters in strings (generic, single quote, shell, bash, bash single)
* unescape: unescape \ escaped chars in strings

This is a Rust reimplementation of some tools found in emonti's
rbkb, itself a Ruby reimplementation of
Matasano's BlackBag.
