Self-contained Go sqlite3 driver with an AES-256 encrypted sqlite3 database

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:

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() to check whether a database file is encrypted or not.

Examples can be found under the ./_example directory
