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

Download and Build sqlcipher

--Skip this if sqlcipher is already installed

Pull the code from https://github.com/sqlcipher/sqlcipher in a directory (say ~/sqlcipher)
mkdir ~/bld;        #  Build will occur in a sibling directory
cd ~/bld;           #  Change to the build directory
../sqlcipher/configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto"; 
                    #configure sqlcipher 

make install;       #  Install the build products

Decrypt the database to a plaintext database

$ 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; 

Find the decrypted database at ~/plaintext.db which you can use with any sqlite browser like this.

Update : September 2015

http://sqlitebrowser.org now supports sqlcipher databases. That's neat.

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

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
  1. 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
  1. 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...

Use SQliteStudio

Select SQLiteChiper and enter the password. The database will be opened.
