go-sqlcipher
==========
[![Build Status](https://travis-ci.org/xeodou/go-sqlcipher.svg?branch=master)](https://travis-ci.org/xeodou/go-sqlcipher)

SQLCipher driver conforming to the built-in database/sql interface and using the latest sqlite3 code.


which is
`3.20.1`

Working with sqlcipher version which is
`3.4.2`

It's wrapper with
 * [go-sqlite3](https://github.com/mattn/go-sqlite3) sqlite3 driver for go that using database/sql.
 * [SQLCipher](https://github.com/sqlcipher/sqlcipher) SQLCipher is an SQLite extension that provides 256 bit AES encryption of database files.
 * Using [openssl](https://github.com/openssl/openssl) as the 256 bit AES encryption.

*Have't build test in a windows machine or linux machine*
**Working in my macbook-air**

Installation
------------

This package can be installed with the go get command:

    go get github.com/xeodou/go-sqlcipher

_go-sqlcipher_ is *cgo* package.
If you want to build your app using go-sqlcipher, you need gcc.
However, if you install _go-sqlcipher_ with `go install github.com/xeodou/go-sqlcipher`, you don't need gcc to build your app anymore.

Documentation
-------------

API documentation can be found here: http://godoc.org/github.com/xeodou/go-sqlcipher

Examples can be found under the `./_example` directory

FAQ

The golang code is copy from [go-sqlite3](https://github.com/mattn/go-sqlite3)
If you have some issue, maybe you can find from https://github.com/mattn/go-sqlite3/issues

Here is some help from go-sqlite3 project.

* Want to build go-sqlite3 with libsqlite3 on my linux.

    Use `go build --tags "libsqlite3 linux"`

* Want to build go-sqlite3 with libsqlite3 on OS X.

    Install sqlite3 from homebrew: `brew install sqlite3`

    Use `go build --tags "libsqlite3 darwin"`

* Want to build go-sqlite3 with icu extension.

   Use `go build --tags "icu"`

   Available extensions: `json1`, `fts5`, `icu`

* Can't build go-sqlite3 on windows 64bit.

    > Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit.
    > See: https://github.com/mattn/go-sqlite3/issues/27

* Getting insert error while query is opened.

    > You can pass some arguments into the connection string, for example, a URI.
    > See: [#39](https://github.com/mattn/go-sqlite3/issues/39)

* Do you want to cross compile? mingw on Linux or Mac?

    > See: [#106](https://github.com/mattn/go-sqlite3/issues/106)
    > See also: http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html

* Want to get time.Time with current locale

    Use `_loc=auto` in SQLite3 filename schema like `file:foo.db?_loc=auto`.

* Can I use this in multiple routines concurrently?

    Yes for readonly. But, No for writable. See [#50](https://github.com/mattn/go-sqlite3/issues/50), [#51](https://github.com/mattn/go-sqlite3/issues/51), [#209](https://github.com/mattn/go-sqlite3/issues/209), [#274](https://github.com/mattn/go-sqlite3/issues/274).

* Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?

    Each connection to :memory: opens a brand new in-memory sql database, so if
    the stdlib's sql engine happens to open another connection and you've only
    specified ":memory:", that connection will see a brand new database. A
    workaround is to use "file::memory:?mode=memory&cache=shared". Every
    connection to this string will point to the same in-memory database. See
    [#204](https://github.com/mattn/go-sqlite3/issues/204) for more info.

* Print some waring messages like `warning: 'RAND_add' is deprecated: first deprecated in OS X 10.7`

    You can ignore these messages.
