- on ARM, use Neon/ACLE extensions (a 3x-4x perf improvement) - on x64 use a plain C implementation from nayuki (a 2x-3x perf gain) Unfortunately, we can't use the dedicated `SHA1` extension on x64 as this became widely available only recently (esp. on AMD CPUs)
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
