Answer 1

This shell script will decrypt a SQLCipher database called mydb.db and create one called mydb-decrypt.db. Params are $1=key, $2, path to read & write from.

#!/bin/bash
echo "Decrypting $2 using key $1"
echo "PRAGMA key='$1';select count(*) from sqlite_master;ATTACH DATABASE '$2/mydb-decrypt.db' AS plaintext KEY '';SELECT sqlcipher_export('plaintext');DETACH DATABASE plaintext;" | sqlcipher $2/mydb.db
echo "Done."

If you wanted to do this in a single command line, the guts of this are:

echo "PRAGMA key='$1';select count(*) from sqlite_master;ATTACH DATABASE '$2/mydb-decrypt.db' AS plaintext KEY '';SELECT sqlcipher_export('plaintext');DETACH DATABASE plaintext;" | sqlcipher $2/mydb.db
