Function base64_encode 

Source 
pub fn base64_encode(input: &str) -> String
Expand description

Encodes text to Base64.

Converts input text to Base64 encoding using the standard RFC 4648 alphabet. This is a lossless encoding that increases the string length by approximately 33% and is commonly used for transmitting binary data or obfuscating payloads.

§Use Cases

  • Red Team: Obfuscate command payloads to evade detection
  • Data Transmission: Safely encode binary data in text formats
  • Blue Team: Test if security systems properly decode Base64
  • API Testing: Encode credentials or tokens

§Examples

use redstr::base64_encode;

assert_eq!(base64_encode("hello"), "aGVsbG8=");
assert_eq!(base64_encode("test"), "dGVzdA==");

// Obfuscate shell commands
let cmd = base64_encode("rm -rf /tmp/*");
assert_eq!(cmd, "cm0gLXJmIC90bXAvKg==");

// Encode credentials
let auth = base64_encode("username:password");
// Use in Authorization: Basic header
