[denji]

SQLCipher is an open source extension to SQLite that provides transparent 256-bit AES encryption of database files.

• https://github.com/sqlcipher/sqlcipher (SQLCipher Community Edition)

  Features

• Fast performance with as little as 5-15% overhead for encryption on many operations
• 100% of data in the database file is encrypted
• Good security practices (CBC mode, key derivation)
• Zero-configuration and application level cryptography
• Algorithms provided by the peer reviewed OpenSSL crypto library.
• Configurable crypto providers

I'm aware of sqlcipher. I wanted to implement authenticated encryption using Go packages, so that's what my API is aimed at. Performance is likely to be worse due to Go -> C -> Go call overhead, but I haven't compared it with sqlcipher.
