- EQL — defines the PostgreSQL objects that store and query encrypted values.
- Stack Encrypt — encrypts values under per-value ZeroKMS data keys and derives searchable terms from them, for Rust and, through a WASI guest, Go.
- EQL → Stack CLI: EQL ships install and uninstall artifacts; the Stack CLI applies them and preserves reconstructable database objects across reinstall.
- EQL → ORM adapters: EQL defines durable encrypted column domains and disposable query machinery; adapters create application columns and derived search indexes against that surface.
- Stack Encrypt → EQL: Stack Encrypt seals values and renders the ZeroKMS
descriptor; EQL's
eql-bindingstranscodes those into EQL payloads, and itsIdentifier(a table and a column) is a two-segment Stack EncryptLabel.
