Cages

Cages are serverless functions hosted on Evervault for processing the data you encrypt with Relay or our SDKs.

Cage.toml Reference

A convenient way to configure your Cages in code.

Overview

The Cage.toml provides a simple way to configure your Cage. Just include a Cage.toml in your deployed Cage, and we'll extract and apply your configuration settings.

Define your Cage configuration in toml with a top level cage key:

toml[cage]
whitelist = ["api.yoursite.com"]
timeout = 120
handler = "main.myFunc"

[cage.playground]
username = "Bob"
creditCardNumber = "1234 5678 9012 3456"
cv2 = 001

Reference

cage.whitelist

Restrict your Cage's network access to specific domains by providing an array of strings.

Default: allow all

toml[cage]
whitelist = ["api.yoursite.com"]
# Alternatively
# cage.whitelist = ["api.yoursite.com"]

cage.timeout

Customize your Cage's timeout by providing a positive integer value. The timeout is specified in seconds.

Default: 30

Maximum: 900

toml[cage]
timeout = 60
# Alternatively
# cage.timeout = 60

cage.handler

Customize your Cage's entry point by specifying the handler in the form <FILE>.<FUNCTION>.

Default: index.handler

toml[cage]
handler = "main.myFunc"
# Alternatively
# cage.handler = "main.myFunc"

cage.playground

Customize the default playground data for your Cage in the Evervault Dashboard. This data will be used to construct the JSON data shown in the Cage Playground and Cage Guides.

Default: { name: "<YOUR_ACCOUNT_NAME>" }

toml[cage.playground]
username = "Bob"
creditCardNumber = "1234 5678 9012 3456"
cv2 = 001
