👑 CONTENTS 👑

The Bashacks pack is organized into several subcategories for easy location of specific functions. Each subcategory addresses a set specific functionalities. Below the main subcategories are available.

These subcategories help organize the package's functionalities, making it easier for users to find and use tools wanted. 🧚

🔐 Crypto

Functions related to cryptography and hash manipulation. (the secret-keeping girlies)

bh_rot — Encrypts/Decrypts a string with the Caesar Cipher using n shifts to the right.
bh_strxor — Calculates the exclusive OR of each character in a string with a key.

For more details, see: file:///usr/share/doc/bashacks-doc/html/crypto.html

📁 Filesystem

This section generally contains functions for file manipulation. (files, but make it organized 💖)

bh_bkp — Performs a quick backup of the file using the current date.
bh_findmime — Finds files by MIME type.
bh_hashes — Generates the md5, sha1, and sha256 message digest of the file or list of files.
bh_md5rename — Converts the filename to the equivalent md5 hash.
bh_secretfile — Use it to compress and send files, automatically generating a password.
bh_sharefile — Loads a file and provides a unique URL to access it without a password.
bh_zipmal — Compresses the file in zip format with password protection. The password is "infected".

bh_dec2bin — Converts decimal to binary.
bh_dec2hex — Converts decimal to hexadecimal.
bh_hex2bin — Converts hexadecimal to binary.

🌐 Net

Network operations and related tools. (the internet is literally right there ✨)

bh_bin2ip — Convert a binary string into a network IP address.
bh_hostcalc — Enter a network CIDR mask and determine the number of hosts.

bh_ipisblocked — Checks if an IP address is blocked by several security vendors, returning [T] if positive and [F] if opposite.
bh_ipinfo — Queries ipinfo.io and returns basic information about an address.
bh_myip — Returns the external IP address of your network connection.
bh_unshort — Reveals the real URL behind shortened links.
bh_wgetr — Operates recursively, building on a previous instance of wget.

For more details, see: file:///usr/share/doc/bashacks-doc/html/net.html
