Functions

func Base64

func Base64(data []byte) string

Base64 encodes data to standard base64.

func Base64Decode

func Base64Decode(s string) ([]byte, error)

Base64Decode decodes a standard base64 string.

func Base64Raw

func Base64Raw(data []byte) string

Base64Raw encodes data to base64 without padding.

func Base64URL

func Base64URL(data []byte) string

Base64URL encodes data to URL-safe base64.

func Hex

func Hex(data []byte) string

Hex encodes data to a hex string.

func HexDecode

func HexDecode(s string) ([]byte, error)

HexDecode decodes a hex string.

func JSON

func JSON(v any) string

JSON serializes a value to a JSON string.

func ROT13

func ROT13(s string) string

ROT13 applies ROT13 substitution cipher.

func URL

func URL(s string) string

URL percent-encodes a string.

func URLDecode

func URLDecode(s string) (string, error)

URLDecode decodes a percent-encoded string.

func URLPath

func URLPath(s string) string

URLPath encodes a string for use in a URL path segment.

func URLRaw

func URLRaw(s string) string

URLRaw percent-encodes a string preserving RFC 3986 unreserved characters. Unlike url.QueryEscape, it encodes spaces as %20 (not +) and only escapes characters that are not in: A-Z a-z 0-9 - _ . ~

func UTF16LE

func UTF16LE(s string) []byte

UTF16LE encodes a string to UTF-16 Little Endian bytes. Used for PowerShell -EncodedCommand.

func XOR

func XOR(data, key []byte) []byte

XOR applies XOR encryption with a repeating key.

Types

type Buffer

type Buffer struct {
	// contains filtered or unexported fields
}

Buffer is a fluent binary packet builder with big-endian encoding. Designed for crafting protocol messages.

func NewBuffer

func NewBuffer() *Buffer

NewBuffer creates a new binary buffer.

func (*Buffer) Build

func (b *Buffer) Build() []byte

Build returns the buffer contents as a byte slice.

func (*Buffer) Byte

func (b *Buffer) Byte(v int) *Buffer

Byte appends a single byte.

func (*Buffer) Bytes

func (b *Buffer) Bytes(v []byte) *Buffer

Bytes appends raw bytes.

func (*Buffer) Len

func (b *Buffer) Len() int

Len returns the current buffer length.
