Go Shellcode Execution Example: Simple XOR Cipher & VirtualAlloc

This is a Go program that reads a binary payload file, encodes it using a simple XOR cipher with a hardcoded key, and then decodes and executes the resulting shellcode.

'The XOR cipher used in this program is not secure, as the key is hardcoded and the algorithm is simple. Additionally, the use of sleep statements in the exec function is not necessary and may cause the program to behave unpredictably.'

Overall, this program appears to be a basic example of shellcode execution in Go, but it should not be used as-is in any production environment.
