Core Methods

Conversion Operations

ToHexString(byte[] bytes)

Converts byte array to hexadecimal string representation.

var bytes = new byte[] { 0x48, 0x65, 0x6C, 0x6C, 0x6F };
var hex = bytes.ToHexString(); // "48656C6C6F"

FromHexString(string hexString)

Converts hexadecimal string to byte array.

var hex = "48656C6C6F";
var bytes = hex.FromHexString(); // [0x48, 0x65, 0x6C, 0x6C, 0x6F]
var text = Encoding.UTF8.GetString(bytes); // "Hello"

Encoding Operations

ToBase64(byte[] bytes)

Converts byte array to Base64 string.

var bytes = Encoding.UTF8.GetBytes("Hello World");
var base64 = bytes.ToBase64(); // "SGVsbG8gV29ybGQ="

FromBase64(string base64String)

Converts Base64 string to byte array.

var base64 = "SGVsbG8gV29ybGQ=";
var bytes = base64.FromBase64();
var text = Encoding.UTF8.GetString(bytes); // "Hello World"

Advanced Operations

Byte Manipulation

XorWith(byte[] bytes, byte[] key)

Performs XOR operation with a key.

var data = Encoding.UTF8.GetBytes("Secret");
var key = new byte[] { 0xAB, 0xCD, 0xEF };
var encrypted = data.XorWith(key);
var decrypted = encrypted.XorWith(key); // Back to original

Analysis Operations

CalculateChecksum(byte[] bytes)

Calculates a simple checksum of the byte array.

var data = Encoding.UTF8.GetBytes("Hello");
var checksum = data.CalculateChecksum(); // Simple sum of all bytes

Best Practices

  1. Memory Management: Be mindful of large byte arrays and memory usage
  2. Encoding Consistency: Always specify encoding when converting strings
  3. Security: Use proper cryptographic functions for sensitive operations
  4. Performance: Consider streaming for large data operations
