System.Data.SQLite: RC4 Chipher

[Miniontoby]

Hi,

Is there support for System.Data.SQLite: RC4 chipher?

I really need it cause I am trying to open a database from another app that was written in C# which uses System.Data.SQLite.

I know the chipher itself is bad, but I cannot change the chipher!

I tried it out, but it doesn't seem to work. Here's the code I tried:

use std::str::FromStr;
use sqlx::{sqlite::SqliteConnectOptions, ConnectOptions};

#[tokio::main(flavor = "current_thread")]
async fn main() -> Result<(), sqlx::Error> {
    let passphrasr = "ENTER_CODE_HERE";

    let mut conn = SqliteConnectOptions::from_str("sqlite://PATH_TO_FILE")?
        .pragma("cipher", "'rc4'")
        .pragma("key", format!("'{}'", passphrasr.replace('\'', "''")))
        .connect()
        .await?;

    sqlx::query(r#"SELECT * from song;"#).execute(&mut conn).await?;

    println!("* Hello, world!");
    Ok(())
}

It gave me the Error: Database(SqliteError { code: 26, message: "file is not a database" }) which means it didn't decrypt the file correctly.

When using nodejs better-sqlite3-multiple-ciphers package it does open correctly when using the same pragma's.

As the README for better-sqlite3-multiple-ciphers explains, it uses the SQLite3MultipleCiphers extension, which is... the exact same thing you linked at the beginning.

The "extension" (since it can't actually load as an extension as it needs a few changes to SQLite itself) works as a drop-in replacement for SQLite3: https://utelle.github.io/SQLite3MultipleCiphers/docs/installation/install_overview/#drop-in-replacement-for-sqlite

You would use this with the sqlite-unbundled feature and point libsqlite3-sys to the built dylib using SQLITE3_LIB_DIR: https://github.com/rusqlite/rusqlite?tab=readme-ov-file#notes-on-building-rusqlite-and-libsqlite3-sys

I can't guarantee that any of this will work without a lot of extra fiddling. You might be better off with the NodeJS lib.

HI,

So my project uses Tauri and SvelteKit and ViteJS.
So I cannot use the NodeJS lib, since I am running inside a browser.

About the using lib thing, I really don't know how to implement that... Like it tells me a bit, but not enough for me to actually pull it off!

Are there any examples with the unbundled stuff and/or sqlcipher feature?

This is the error I got when trying to use rusqlite = { version = "0.32.1", features = ["bundled-sqlcipher"] }

error: failed to run custom build command for `libsqlite3-sys v0.30.1`

The bundled-sqlcipher-vendored-openssl one requires me to have perl installed, which I do not have, and cannot install cause too less space left...

Also I cannot use prebuilt stuff, cause rust requires .lib and the only files I can find are .dll

Update: Well perhaps I will just make a CLI command using the nodejs lib and then just use that... but it wouldn't be the best way to do it tho... but maybe that will work...
