How to decrypt an encrypted sqlcipher database file on command line?

Question

The question is simple

What I have is:

• I have a database file which is encrypted using sqlcipher.
• I also

Answer 1

Building on the previous answers , I have a comprehensive answer. I have the configuration- OS X version - 10.10.4 Steps : 1. Donwload and build OpenSSL code:

$ curl -o openssl-1.0.0e.tar.gz https://www.openssl.org/source/openssl-1.0.0e.tar.gz
$ tar xzf openssl-1.0.0e.tar.gz
$ cd openssl-1.0.0e
$ ./Configure darwin64-x86_64-cc
$ make

2. Download and build SQLCipher code.

In another directory,

$ git clone https://github.com/sqlcipher/sqlcipher.git
$ cd sqlcipher

Change '/path/to/libcrypto.a' in the following command to your path

$ ./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="/path/to/libcrypto.a"
$ make

3. Decrypt to plaintext database (As illustrated in previous post by Vinay)

   $ cd ~/;
   $ ./sqlcipher encrypted.db 
   sqlite> PRAGMA key = 'testkey'; 
   sqlite> ATTACH DATABASE 'plaintext.db' AS plaintext KEY '';  -- empty key will disable encryption
   sqlite> SELECT sqlcipher_export('plaintext');
   sqlite> DETACH DATABASE plaintext;
   

Tis should help you decrypt the encrypted file...
