vortex-mod-containers

WASM plugin for Vortex — decrypts the JDownloader-era link containers and parses the Metalink standard.

Supported formats

Format	Extension(s)	Spec / source	Status
DLC	.dlc	JDownloader v1, AES-128-CBC, embedded historic key	✅
CCF	.ccf	Cryptload v1, AES-128-CBC, magic CCF1\n	✅
RSDF	.rsdf	RapidShare legacy, AES-128-CBC, hex line per URL	✅
Metalink	.metalink, .meta4	RFC 5854 (v4) + community v3	✅

See docs/ADR-001-container-keys.md for the rationale behind embedded keys and the explicit choice to not call out to service.jdownloader.org.

Plugin contract

The host invokes three exports after the user drops a file in the Link Grabber:

Export	Input	Output
can_decrypt	bytes	"true" / "false"
detect	bytes	JSON { "format": "dlc" | "ccf" | "rsdf" | "metalink" | null }
decrypt	bytes	JSON { "format", "links": [{url, filename?, sizeBytes?, mirrors[], checksums[]}] }

The plugin owns no networking — it transforms bytes into a structured link list. The host then routes each ContainerLink through the regular hoster pipeline.

Build

rustup target add wasm32-wasip1
cargo build --target wasm32-wasip1 --release

# Output:
#   target/wasm32-wasip1/release/vortex_mod_containers.wasm
sha256sum target/wasm32-wasip1/release/vortex_mod_containers.wasm

Test

cargo test            # native — 60+ unit + integration tests
cargo clippy --all-targets -- -D warnings

The integration suite (tests/synthetic_corpus.rs) generates a 20-container fixture covering all four formats and round-trips them through the public decrypt() API.
