SQLite does not support encryption or passwords. There are a few extensions that add the capability for encryption, among these are The SQLite Encrytion Extension (SEE), SQLite-Crypt, wxsqlite3 and SQLCipher.
However none of these provides with the tcl bindings to be able to manipulate an SQLite database from tcl code.
I will show you how to achieve this, but it will take a bit of work.
You need to download MinGW/MSYS, OpenSSL and the SQLCipher source code.
After that follow these steps:
1. install MinGW/MSYS
2. install OpenSSL (requires Visual C++ 2008 Redistributables)
3. create an sqlcipher directory and place all the files from the SQLCipher zip
4. copy openSSL/bin/libeay32.dll to sqlcipher directory.
5. copy openSSL/lib/MinGW to /MinGW/lib directory.
6. go to the sqlcipher directory and compile using the following command:<
>`./configure CFLAGS="-DSQLITE_HAS_CODEC -I/c/openssl/include" LDFLAGS="-leay32 -L/c/openssl/lib" `
7. type make
8. type make dll
These will create an sqlite3.exe and sqlite3.dll with tcl bindings.
When trying to encrypt a database just type: PRAGMA key = 'password'
That's all.
