## go-sqlcipher [](http://godoc.org/github.com/mutecomm/go-sqlcipher) [](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.
|
