description: Create and open end-to-end encrypted Crypstie links with the crypstie npm CLI. Use when an agent must securely exchange text or files through crypstie.com, decrypt an existing Crypstie URL without a browser, create reusable or burn-on-read links, or automate Crypstie from a shell.

# Crypstie
|
|
|
|
Use the `crypstie` CLI. Install it with `npm install --global crypstie` if the
|
|
command is unavailable.
|
|
|
|
## Open a link
|
|
|
|
Quote URLs because they contain `#`:
|
|
|
|
```shell
|
|
crypstie open "$CRYPSTIE_URL"
|
|
```
|
|
|
|
Write binary content directly to a file:
|
|
|
|
```shell
|
|
crypstie open "$CRYPSTIE_URL" --output ./result.bin
|
|
```
|
|
|
|
Use `--json` only when metadata or Base64 data is required.
|
|
|
|
## Create a link
|
|
|
|
Pipe text without making a temporary plaintext file:
|
|
|
|
```shell
|
|
printf '%s' "$CONTENT" | crypstie create
|
|
```
|
|
|
|
Create from a file and set lifetime:
|
|
|
|
```shell
|
|
crypstie create ./input.bin --days 7
|
|
```
|
|
|
|
Add `--burn` only when the user requests deletion after reading.
|
|
|
|
## Handle secrets
|
|
|
|
- Treat the complete URL as a secret: anyone holding it can decrypt the data.
|
|
- Never omit the fragment after `#`; it contains the local decryption key.
|
|
- Avoid repeating a full URL in explanations, logs, issues, or source files.
|
|
- Return a newly created URL only to the requesting user.
|
|
- Prefer environment variables when opening links in automation.
|
|
- Remember that Crypstie protects stored content, not endpoints where plaintext
|
|
is read or written.
