sqlcipher-src

The SQLCipher amalgamation as C source for -sys crates, on native targets and on wasm32-unknown-unknown through sqlite-wasm-rs, where it adds the libtomcrypt crypto provider.

Native builds compile AMALGAMATION_FILE with their own crypto provider and flags:

let dir = sqlcipher_src::source_dir();
assert!(dir.join(sqlcipher_src::AMALGAMATION_FILE).is_file());
assert!(dir.join(sqlcipher_src::HEADER_FILE).is_file());

sqlite-wasm-rs 0.6 compiles WASM_SOURCE_FILE instead of plain SQLite when SQLITE_WASM_RS_SOURCE_DIR points at the same directory, set in the environment or in [env] of .cargo/config.toml:

export SQLITE_WASM_RS_SOURCE_DIR="$(cargo metadata --format-version 1 \
  | jq -r '.packages[] | select(.name == "sqlcipher-src") | .manifest_path' \
  | xargs dirname)/sqlcipher"
cargo build --target wasm32-unknown-unknown

Shared-memory builds (+atomics) also need -mbulk-memory in CFLAGS_wasm32_unknown_unknown.

The sources are generated from signed SQLCipher and libtomcrypt releases by upgrade.sh. CI runs rusqlite's SQLCipher tests on them natively, and checks that files written natively and in Node, Chrome and Firefox open on both sides.

The wrapper is MIT, SQLCipher is BSD-3-Clause, SQLite is public domain, and libtomcrypt is public domain or WTFPL.
