Are you looking to learn how to encrypt files with B64 Crypter and understand how encryption can bypass antivirus detection? This blog article will introduce you to B64 Crypter, a tool designed by Tigerzplace, and explain how it works. Whether you’re a cybersecurity enthusiast or an ethical hacker, mastering encryption techniques is essential for understanding how to secure files and explore cryptographic concepts.
In this article, I’ll share my experience of creating the B64 Crypter, reflecting on my early methods of crypting a RAT (Remote Access Trojan) server. Initially, this was a manual process, but I’ve since automated it with the development of this crypter. Now, I’m sharing the tool for educational purposes.
Encrypt Files with B64 Crypter
What is B64 Crypter?
B64 Crypter is a tool that automates the encryption of executable files using Base64 encoding and other techniques. Its primary function is to obscure the code of an executable file, making it more difficult for antivirus programs to detect. This type of tool is used by ethical hackers and cybersecurity experts to test systems and understand where antivirus programs might fail.
However, B64 Crypter is intended for learning purposes, not for malicious activities. This article will demonstrate how to encrypt any executable file using B64 Crypter and how you can use this tool to explore encryption techniques.
How B64 Crypter Works
B64 Crypter encrypts files by transforming them into Base64-encoded strings, reversing those strings, and then embedding the obfuscated data into a PowerShell script executed via VBS (Visual Basic Script). Base64 is a widely-used encoding scheme that converts binary data into ASCII text, making it easier to handle and transmit. The combination of PowerShell and VBS allows the file to be executed on Windows systems while remaining hidden from antivirus detection.
By leveraging these techniques, the encrypted file can still perform its intended functions while bypassing traditional detection methods used by antivirus programs.
Why Use B64 Crypter for Educational Purposes
B64 Crypter is a powerful learning tool for those interested in cybersecurity and encryption techniques. Here’s why:
- Understand Antivirus Evasion: By using B64 Crypter, you can see firsthand how antivirus programs detect files based on their behavior and signature. By encrypting a file, these signatures are altered, making the file undetectable to antivirus software.
- PowerShell and VBS Script Execution: Learn how PowerShell and VBS scripts are used to execute code on Windows systems. These scripts are common in both legitimate and malicious software. By understanding them, you’ll be better equipped to defend against cyber threats.
- Ethical Hacking Insight: B64 Crypter shows how ethical hackers and cybersecurity professionals might test systems for vulnerabilities, ensuring the security of files and systems.
Important: The use of B64 Crypter should only be for educational and ethical hacking purposes. Do not use it to encrypt malicious files or for illegal activities.
How to Encrypt a File with B64 Crypter
To illustrate how B64 Crypter works, let’s walk through an example where we encrypt a RAT file. Although this tool can encrypt any executable file, we’ll focus on the RAT file for demonstration purposes.
Step 1: Install Python
- First, make sure you have Python 3. x installed on your system. B64 Crypter is written in Python, so you’ll need Python to run it. You can download Python from the official Python website.
Step 2: Download B64 Crypter
- Next, download the B64 Crypter:
. - After downloading, extract the files. You’ll find a
words.txtfile inside the folder—don’t delete this as it’s required for the crypter to function.
Step 3: Run the Crypter
- Once the files are extracted, open Command Prompt or a terminal in the same folder. Run the crypter by entering the appropriate command or double-clicking the crypter file. A terminal window will open.
Step 4: Encrypt Your File
- Drag the file you want to encrypt into the terminal or enter its file path manually. B64 Crypter will encrypt the file using Base64 encoding and prepare it for execution. You can also specify additional options, such as whether to place the file in the startup folder (if you’re working with RAT files).
How Antivirus Software is Bypassed
Antivirus programs rely heavily on file signatures to detect malware. When you encrypt a file with B64 Crypter, the file’s signature is obfuscated, making it difficult for the antivirus to recognize the file as malicious. By encoding the file using Base64 and embedding it in a PowerShell script, the antivirus software is confused and often fails to detect the file during runtime.

This method is not limited to RAT files—you can encrypt various executable files and observe how antivirus software responds.
Ethical Hacking and Cybersecurity Training
For those interested in ethical hacking and penetration testing, B64 Crypter provides an excellent opportunity to learn how encryption and antivirus evasion techniques work. The skills you develop while experimenting with these tools will be invaluable as you advance in cybersecurity.
