## Unofficial AppImage Directory

This repository exists to contribute to the AppImage ecosystem, with a special focus on supporting **AM** (AppImage Manager / Appman) users.

It aims to:
- Provide high-quality, unofficial AppImages for applications that lack native AppImage releases from their upstream developers.
- Fill distribution gaps by converting selected apps into AppImages.
- Host them here with signed verification files (BUILD_INFO.json + .asc) so users can easily download and trust the builds for use in AM/Appman.

## Verifying the AppImage

All AppImages in this repository are built directly from the official source code releases and include a signed authenticity proof (manifest + GPG signature) to confirm they are unchanged and come from my trusted build process.

### One-time setup (do this once)
Import the builder's public key from the repository root:
```bash
wget https://git.yourittech.support/yourittech.support/appimages/raw/branch/main/builder-pubkey.asc
gpg --import builder-pubkey.asc
```

### Verify a downloaded file (e.g. Nextcloud-Talk-v2.1.1-x86_64.AppImage)

1. Download these three files from the version folder (e.g. `/nextcloud_talk/v2.1.1/`):
- `Nextcloud-Talk-v2.1.1-x86_64.AppImage`
- `BUILD_INFO-Nextcloud-Talk-v2.1.1.json`
- `BUILD_INFO-Nextcloud-Talk-v2.1.1.json.asc`

2. Check the AppImage integrity with SHA256:
```bash
sha256sum Nextcloud-Talk-v2.1.1-x86_64.AppImage
```
Compare the output to the value of `appimage_sha256` inside the `BUILD_INFO-Nextcloud-Talk-v2.1.1.json` file.

3. Verify the signed manifest (confirms the SHA256 and build info come from me):
```bash
gpg --verify BUILD_INFO-Nextcloud-Talk-v2.1.1.json.asc BUILD_INFO-Nextcloud-Talk-v2.1.1.json
```
Look for:
```
gpg: Good signature from "YourITtech.support" [...]
```
> The warning 'This key is not certified with a trusted signature' is normal for a personal builder key and can be safely ignored; the important confirmation is the 'Good signature' line, which means the manifest file is authentic and unchanged from my signed build process.
