BullDDoser Posted March 26 Posted March 26 Hello Everyone, Today i am goin to share you my simple file crypter coded in C# using VB.NET 4.8. This community gave me a lot of experience and knowledge so its nice to give something back... Now, you may ask why name DumDumCrypter? Its because the application and its functionalities are so dumb. :D Overall Functionality File Encryption: Allows users to select a file and encrypt it using AES encryption. The encryption key can be manually provided or randomly generated. Stub Generation: Generates a C# stub source code containing the encrypted file data in Base64 format, split into parts. The stub source code can optionally include additional code for obfuscation. The stub source code can optionally include startup code to add the executable to the startup folder. Stub Compilation: Compiles the generated stub source code into an executable. Optionally changes the icon of the compiled executable. Optionally clones assembly information, removes the manifest, or clones icons from a source assembly. Detailed Steps File Selection: User selects a file to be encrypted. The file path is displayed in a text box Encryption Key: User can provide an encryption key or generate a random one. The key is displayed in a text box. Encrypt File: The selected file is read into a byte array. The file bytes are encrypted using AES encryption with the provided key. The encrypted bytes are split into five parts and converted to Base64 strings. Generate Stub Source: A template for the stub source code is loaded. The Base64 strings are inserted into the template. Additional code and startup code are conditionally added based on user selections. Compile Stub: The modified stub source code is compiled into an executable via CodeDom. The icon of the executable can be changed if an icon file is provided. Assembly information can be cloned, the manifest can be removed, and icons can be cloned from a source assembly if selected.

Special Thanks goes to Nodes and Py_Dev for great ideas which they posted on forum and made this project possible VM und Virusscan ist euer Freund 2 Quote Ich bin nur in einem unter den Namen BullDDoSer a.k.a.
