# ctfetch

Tools for working with Certificate Transparency log tiles.

## Install

```bash
go install ./cmd/ctfetch
go install ./cmd/tiledump
```

## Commands

### ctfetch

Fetch and dump leaf entries from CT logs.

```bash
ctfetch [--dumpall] <log-url> <leaf-index>
```

**Examples:**

Dump a specific entry:
```bash
ctfetch https://halloumi2026h1.mon.ct.ipng.ch 629794635
```

Dump all entries in the tile:
```bash
ctfetch --dumpall https://halloumi2026h1.mon.ct.ipng.ch 629794635
```

**Options:**
- `--dumpall`: Dump all entries in the tile instead of just the specified leaf

### tiledump

Read a CT log tile file or URL and dump contents. Automatically detects and handles both data tiles (log entries) and hash tiles (Merkle tree hashes).

```bash
tiledump <tile-file-or-url>
```

**Examples:**

Data tile from a file:
```bash
tiledump tile.data
```

Data tile from a URL:
```bash
tiledump https://halloumi2026h1.mon.ct.ipng.ch/tile/data/x002/x460/135
```

Hash tile from a URL:
```bash
tiledump https://halloumi2026h1.mon.ct.ipng.ch/tile/0/x100/999
```
