MemeEncryption README.md

Introduction

This PowerShell script provides a unique way to encrypt and decrypt files using a custom algorithm. The goal was to test if custom encryption was more effective in avoiding AV detection.

Features

• Custom Encryption Algorithm: Uses a combination of XOR operations and a fixed key for encryption.
• Base64 Encoding: Encrypted data is encoded in Base64, making it suitable for storage or transmission in text form.
• Encrypt and Decrypt Files: Functions to encrypt and decrypt files, with the encrypted file having a .meme extension.
• PowerShell Based: Easy to run and integrate into existing PowerShell workflows.

Functions

1. MemeEncrypt($inputString): Encrypts a given string using the custom algorithm.
2. CustomDecrypt($encryptedString): Decrypts a string encrypted by the MemeEncrypt function.
3. EF($FP): Encrypts the content of a file at the given file path.
4. DF($encryptedFilePath): Decrypts a file encrypted by the EF function.

How to Use

1. Encrypt a File: Call the EF function with the file path as an argument.

   $FP = "path_to_your_file"
   EF $FP

   This will create an encrypted file with the .meme extension.

2. Decrypt a File: Call the DF function with the path to the encrypted .meme file.

   DF "path_to_your_file.meme"

   This will restore the file to its original form.

Requirements

• PowerShell 5.0 or higher.

Security Note

While MemeEncryption adds a fun twist to file encryption, it's important to note that the fixed key "YouHaveBeenDabbedOnGoodSir" is hardcoded into the script. For serious security applications, consider using a more robust encryption method or modifying the script to use a dynamic key.
