## go-sqlcipher [![GoDoc](http://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](http://godoc.org/github.com/mutecomm/go-sqlcipher) [![Build Status](http://img.shields.io/travis/mutecomm/go-sqlcipher.svg?style=flat-square)](https://travis-ci.org/mutecomm/go-sqlcipher)

### Description

Self-contained Go sqlite3 driver with an AES-256 encrypted sqlite3 database
conforming to the built-in database/sql interface. It is based on:

- stripped-down Go sqlite3 driver: https://github.com/mattn/go-sqlite3
- SQLite extension with AES-256 codec: https://github.com/sqlcipher/sqlcipher
- AES-256 implementation from: https://github.com/libtom/libtomcrypt

SQLite itself is part of SQLCipher.

go-sqlcipher currently only supports the SQLCipher 3.x releases.


### Installation

This package can be installed with the go get command:

    go get github.com/mutecomm/go-sqlcipher


### Documentation

To create and open encrypted database files use the following DSN parameters:

```go
key := "2DD29CA851E7B56E4697B0E1F08507293D761A05CE4D1B628663F411A8086D99"
dbname := fmt.Sprintf("db?_pragma_key=x'%s'&_pragma_cipher_page_size=4096", key)
db, _ := sql.Open("sqlite3", dbname)
```

`_pragma_key` is the hex encoded 32 byte key (must be 64 characters long).
`_pragma_cipher_page_size` is the page size of the encrypted database (set if
you want a different value than the default 1024 bytes).

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

Use the function
[sqlite3.IsEncrypted()](https://godoc.org/github.com/mutecomm/go-sqlcipher#IsEncrypted)
to check whether a database file is encrypted or not.

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