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.
    bh_hashcrack - Analyzes various types of hashes. 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.
    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 "virus". For more details, see: file:///usr/share/doc/bashacks-doc/html/filesystem.html

Math
Mathematical operations functions.
    bh_bin2dec - Converts binary to decimal. bh_charcalc - Performs operations with characters (char). bh_dec2bin - Converts decimal to binary. bh_dec2hex - Converts decimal to hexadecimal. bh_hex2bi - Converts hexadecimal to binary. bh_hex2dec - Converts hexadecimal to decimal. bh_hexcalc - In the same way as bh_charcalc, however, works here with hexdigits. For more details, see: file:///usr/share/doc/bashacks-doc/html/math.html

Net
Network operations and related tools.
    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_ip2bin - Convert a network IP address into a binary string. bh_myip - Returns the external IP address of your network connection. bh_wgetr - Operates recursively, building on a previous instance of wget. bh_ipinfo - Queries ipinfo.io and returns basic information about an address. bh_unshort - Makes it possible to unzip a URL. bh_ipisblacklisted - Finds the IP on a blacklist, returning [T] if positive and [F] if opposite. For more details, see: file:///usr/share/doc/bashacks-doc/html/net.html

Programming
Session for the creation of facilitators for development in cli
    bh_skel_c - Generates on the standard output a "C" skeleton. bh_skel_go - Generates on the standard output a "go" skeleton. bh_skel_latex - Generates on the standard output a "LaTeX" skeleton. bh_skel_python - Generates on the standard output a "python" skeleton. bh_skel_yara - Generates on the standard output a "yara" skeleton. For more details, see: file:///usr/share/doc/bashacks-doc/html/programming.html

Reversing
Reverse engineering utilities
    bh_asmgrep - With the binary, attempts to find assembly instructions and prints 4 lines around. bh_asminfo - Displays information about assembly instructions. Internet connection is required for help. bh_replacestring - Finds and replaces occurrences of a string in the file. bh_zerostring - Replaces occurrences with zero bytes in a block or a common file. For more details, see: file:///usr/share/doc/bashacks-doc/html/reversing.html

String
Functions for string manipulation.
    bh_asc2dec - Performs the conversion of a character into its decimal equivalent. bh_asciitable - Displays the ASCII table in the terminal. bh_dec2asc - Equivalent in ASCII for decimal numbers. bh_hex2str - Converts one or more bytes into a hex string. bh_str2dec - Converts one or more bytes to their decimal equivalent. bh_str2hexr - Converts a string to its hex byte equivalent for each character (hex string). bh_str2hex - Converts a string to its hex byte equivalent for each character (hex string). bh_urldecode - Decodes strings to web standard human-readable format. bh_urlencode - Encodes strings with bh_urlencode to web standard. bh_utf8table - Displays the UTF-8 table. For more details, see: file:///usr/share/doc/bashacks-doc/html/string.html
