function Emoji64 { <# .SYNOPSIS Encodes a message using emojis based on a specified pattern. .DESCRIPTION This function encodes a message into a sequence of emojis using a custom pattern. It imports the 'emoji' module to map ASCII characters from the message to corresponding emojis based on the specified pattern. .PARAMETER Message Specifies the message to be encoded into emojis. .PARAMETER Pattern Specifies the pattern of emojis to be used for encoding the message. The function selects emojis from this pattern to represent ASCII characters in the message. .PARAMETER indexStart Specifies the starting index in the emoji pattern from which to begin encoding. Defaults to 0. .EXAMPLE Emoji64 -Message 'this is the secret message!' -Pattern 'music' -indexStart 2 This example encodes the message 'this is the secret message!' into emojis using the 'music' pattern, starting from the third emoji in the pattern. .NOTES This function requires the 'emoji' module to be installed. You can install it using the following command: Install-Module -Name emoji .LINK https://github.com/StartAutomating/Emoji .LINK https://github.com/Unit-259/emoji.64 #> param ( [string]$Message, [string]$Pattern, [int]$indexStart = 0 ) # Determine the starting and ending indices for selecting emojis from the pattern $indexEnd = $indexStart + 63 $message = [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($message)) # Retrieve the emojis corresponding to the selected indices $mapKeys = ((Find-Emoji -Pattern $Pattern)[$indexStart..$indexEnd]).Emoji # Map ASCII characters from the message to the retrieved emojis $encodedMessage = foreach ($char in $Message.ToCharArray()) { $asciiValue = [int][char]$char if ($asciiValue -ge 32 -and $asciiValue -le 126) { $musicNoteIndex = ($asciiValue - 32) % $mapKeys.Count $mapKeys[$musicNoteIndex] } else { $char } } # Output the encoded message return $encodedMessage -join '' } |
