pysqlsimplecipher

Encrypt or decrypt formated sqlite db.

This project is a tool for sqlite database encryption or decryption like sqlcipher without install sqlcipher.

When encrypt or decrypt database, an algorithm called AES-256-CBC is used. Each page shares the same key derived from password, but owns a random initialization vector stored at the end of the page.

Decrypt

python decrypt.py encrypted.db password output.db

Encrypt

python encrypt.py plain.db password output.db

Needs reserved space at the end of each page of the database file.

Otherwise, use sqlcipher to encrypt.

Encrypt with sqlcipher

• Open plain db

./sqlcipher plain.db

• Encrypt to enc.db

ATTACH DATABASE 'enc.db' as encrypted key 'testkey';
SELECT sqlcipher_export('encrypted');
DETACH DATABASE encrypted;
