# Base32 Encode

> Use this Base32 encoder to convert text or encoded bytes to RFC 4648 Base32. Encode text to Base32 with standard padding, then copy the result.

This **Base32 encoder** converts text or encoded input bytes to RFC 4648 Base32. It returns the standard uppercase alphabet with padding where needed, making byte values convenient to paste into a text field or test fixture.

## Key Features

- Encode bytes using RFC 4648 Base32
- Accept text, Hex, or Base64 source bytes
- Return uppercase Base32 with required padding
- Update with Auto / Live or run manually
- Copy output and clear text

## Parameters & Interface Controls

### Input Parameters & Options
- `input_text`: Input text.
- `input_encoding`: `Hex` | `Hex (Ignore Non-Hex Characters)` | `Base64` | `UTF-8` | `UTF-16LE` | `UTF-16BE` | `Windows-1251 (Cyrillic)` | `Windows-1252 (Latin 1)` | ... (42 options)

### Output Fields & Metrics
- `result`: Base32 Encode Result.

- **Controls:** `Run`, `Clear`, `Copy`, `Fill test data`, `Auto / Live`

## Interactive Example (Test Vector)

**Settings:**
- Input Encoding: `UTF-8`

**Input text:**
```text
foobar
```

**Base32 Encode Result:**
```text
MZXW6YTBOI======
```

## How to use Base32 Encode

Use the following steps to process a small test input.

### Encode data as Base32

1. **Enter the data:** Paste the source into Input text. Use normal text, or supply bytes already represented as Hex or Base64.
2. **Set the source encoding:** Set Input Encoding: to UTF-8 for ordinary text, Hex for hexadecimal bytes, or Base64 for Base64-encoded bytes.
3. **Run the calculation:** Leave Auto / Live on to update the result as you edit. To run manually, turn it off and click Run.
4. **Read the encoded value:** Read Base32 Encode Result. Keep any trailing padding characters when passing the value to this site’s decoder.
5. **Copy or clear the text:** Click Copy to copy the result. Use Clear where shown, or the field clear controls, to remove the text.

`foobar` with Input Encoding: UTF-8 becomes `MZXW6YTBOI======`. Hex input `666f6f626172` produces the same result when Hex is selected.

> A rejected request may leave an earlier result visible. Clear the fields and recheck the input before relying on a new calculation.

### Use the standard Base32 alphabet

The result uses A–Z and 2–7, with equals signs to complete the final eight-character group when required. This is standard Base32, not Base32hex or Crockford Base32. There is no alphabet or padding switch.

### Represent bytes without hiding them

Encoding preserves the bytes in a printable representation. It does not encrypt the data, compress it, or add an authentication check. Anyone with a decoder can recover the represented bytes.

## Frequently asked questions

### Which Base32 variant does this encoder use?
It uses the RFC 4648 standard alphabet A–Z and 2–7. Base32hex and Crockford variants are not exposed.

### Why are there equals signs at the end?
Padding completes the final encoded group when the input length requires it. This encoder includes that padding automatically.

### Can I encode Hex or Base64 input?
Yes. Choose its representation under Input Encoding: so the value is decoded to bytes before Base32 encoding.

### Can I disable padding or lowercase the output?
The form has no padding or output-case option. It produces the standard uppercase, padded representation.

### Is Base32 encryption or a TOTP generator?
No. It represents bytes as text. It does not encrypt a secret, generate a random secret, or calculate one-time passwords.

### Is the calculation performed only in my browser?
No. This form sends the entered data to the calculation API. Use sample data instead of production secrets.
