[ANN] luasqleet - a Lua binding to Sqleet, an encrypted SQLite3

[Phil Leblanc <philanc@...>]

Sqleet is a cool encryption extension for SQLite, written by github
user Resilar. It is a very nice and easy to read implementation of a
SQLite encryption codec (much simpler than for example SQLCipher).

See https://github.com/philanc/luasqleet

A sqleet database is a sqlite3 database which is encrypted on disk.
Database pages are transparently decrypted and encrypted when they are
read from and written to the disk; so the database content on disk is
permanently encrypted.

Sqleet uses Chacha20 / Poly1305 for authenticated encryption.

This binding, Luasqleet,  uses the lsqlite3 driver written by Tiago
Dionizio and Doug Currie.  The Luasqleet API is identical to lsqlite3.

Luasqleet includes the SQLite amalgamation (sqlite3 version 3.31.1)
and the crypto implementation, so the Lua module luasqleet.so can be
built without any other dependency.

This is an alpha version, built and tested on Linux with Lua 5.3.
