MoneyMoney is a convenient online banking application for macOS, most useful if you have accounts with multiple different German banks. I wanted to export some of the data I had stored there in a format that the app didn’t support by itself, so I was wondering if I could pull it straight from the database. You can go to the Help menu and click Show Database in Finder and will be led to ~/Library/Containers/com.moneymoney-app.retail/Data/Library/Application Support/MoneyMoney/Database/MoneyMoney.sqlite. If you go to MoneyMoney’s About screen, you’ll see that it attributes SQLCipher.
So, download and compile SQLCipher like this:
git clone https://github.com/sqlcipher/sqlcipher.git cd sqlcipher ./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-L/opt/local/lib -lcrypto" CC=clang CXX=clang++ make -j 4
Now you can open the database using
./sqlcipher "file://$HOME/Library/Containers/com.moneymoney-app.retail/Data/Library/Application Support/MoneyMoney/Database/MoneyMoney.sqlite?mode=ro"
and decrypt and dump it by typing the following commands at the SQLite prompt:
PRAGMA key = '<your database password>'; PRAGMA cipher_compatibility = 3; .dump
The database password is just what you set in MoneyMoney and I figured out the compatibility level by trial and error. It seems like MoneyMoney didn’t yet get around to upgrading to SQLCipher 4, which was released in late 2018. It’s entirely possible that some older versions of MoneyMoney require a lower compatibility level and that some future version may be using level 4.
Disclaimer: You should not attempt to modify the database as that may cause MoneyMoney’s data to become inconsistent or modified in ways the developer did not anticipate. That’s why I open the file in read-only mode above. If you do modify it, you’re on your own.
