## 🧰 Supported Formats

### Common Encodings

- **Base64** - Standard encoding for binary data

  - Example: `Hello` → `SGVsbG8=`

- **Base58** - Bitcoin-style compact format (58-character alphabet)

  - Example: `Hello` → `9Ajdvzr`

- **Base45** - Used in COVID-19 digital certificates

  - Example: `Hello` → `96%DV 2L`

- **Base32** - RFC 4648 compliant encoding

  - Example: `Hello` → `JBSWY3DP`

- **Hexadecimal** - Base-16 representation of binary data

  - Example: `Hello` → `48656c6c6f`

- **Binary** - Base-2 representation of data

  - Example: `Hello` → `01001000 01100101 01101100 01101100 01101111`

- **Morse Code** - Telegraph communication system using dots and dashes

  - Example: `Hello` → `.... . .-.. .-.. ---`

- **URL Encoding** - For URLs and URI components

  - Example: `Hello World` → `Hello%20World`

- **HTML Entities** - Special character conversion

  - Example: `` → `&lt;script&gt;`

- **Punycode** - IDN encoding (RFC 3492)

  - Example: `مثال.جوردان` → `xn--mgbh0fb.xn--mgbjjh1ii`

### Cryptographic & Historical Ciphers

- **JWT** - JSON Web Token encoding/decoding

  - Example: `{"user":"john"}` → `eyJhbGciOiJIUzI1NiJ9.eyJ1c2VyIjoiam9obiJ9.Gpz_UF_YoEEwn4O8U9X0iG1Y_UqvQQYU1gQy7Gxw2BI`

- **Caesar Cipher** - Classical shift cipher

  - Example: `Hello` → `Khoor` (shift: 3)

- **Vigenère Cipher** - Polyalphabetic substitution

  - Example: `Hello` → `Rijvs` (key: "KEY")

- **Hill Cipher** - Matrix-based polygraphic substitution

  - Example: `Hello` → `AXDDTC` (key matrix: [[2,3],[1,4]])

- **ADFGVX Cipher** - WWI German military cipher

  - Example: `Attack` → `VGVADADVGAGA` (key: "KEY")

- **ROT13** - Simple letter substitution

  - Example: `Hello` → `Uryyb`

- **Playfair Cipher** - Historical digraph substitution (1854)

  - Example: `Hello` → `KGAA` (key: "PLAYFAIR")

- **ASCII85** - Compact PostScript encoding

  - Example: `Hello` → `<~87cURDZ~>`
