PySQLcrypt

PySQLcrypt is an enhanced version of PySQLite that uses SQLcrypt, which itself enhances SQLite version 3 with transparent AES encryption.

This demo distribution for Windows is built from the trial version of SQLcrypt and contains the following files:

_sqlcrypt.pyd            
sqlcrypt/*.py            
crypt_test.py            
crypt_dbapi_txns.py

First, copy _sqlcrypt.pyd and sqlcrypt/*.py into your Python installation's site-packages.

Next, run the unit tests in crypt_test.py:

  C:\> python crypt_test.py
  .........
  ----------------------------------------------------------------------
  Ran 9 tests in 0.660s

  OK

Now try out crypt_dbapi_txns.py. This program is based on dbapi_transactions.py from PySQLite, with the following changes: (1) the database file, 'customerdb', is encrypted; (2) at the end of the program run, the database content is not cleared.

  C:\> python crypt_dbapi_txns.py

  C:\> sqlcrypt3 customerdb
  SQLcrypt version 3.0.7
  Enter ".help" for instructions

  C:\> sqlite3 customerdb "select * from orders"
