## What it is
Charm is a Go library and CLI tool that provided client access to Charm Cloud, a hosted service offering encrypted key-value storage, linked identities via SSH keys, and related utilities. Charm Cloud was sunset in November 2024, but the code remains open source and can be self-hosted.

## Use cases
- self-host an encrypted cloud storage backend for Glow and Skate
- add SSH key-based identity and encryption to a Go application
- sync small key-value data across machines with end-to-end encryption
- run a private replacement for the discontinued Charm Cloud service

## When to choose
- you want to self-host the backend that older versions of Glow or Skate connected to
- you need a small Go library for SSH-key-based identity and encrypted data storage
- you want to fork and maintain a lightweight cloud sync service

## When to avoid
- you expect a hosted cloud service - Charm Cloud was sunset in November 2024
- you need active development or new features - the project is in maintenance mode
- you use recent versions of Glow or Skate, which have removed Charm Cloud integration

## Facets
- artifact type: library
- maturity: maintenance
- function: cryptography, auth, cli, sdk
- domain: developer-tools, self-hosted, privacy
- platform: go, cli, cross-platform, self-hosted
