timelock-sh SKILL.md skillA
timelock-sh from brenorb/freedom-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add brenorb/freedom-skills/timelock-sh@git:20261019.ecabd70Pins git:20261019.ecabd70 in mdr.lock. Pin the fingerprint instead.

Use this skill when the user wants to time-lock a local file with timelock.sh so it can only be decrypted after a specific UTC minute, or when you need to inspect, decrypt, or troubleshoot a timelock.sh CMS `.enc` file from the command line without an SDK or account.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# timelock-sh Use the bundled wrapper around `timelock.sh` and local OpenSSL 3.x to encrypt a file for release at a future UTC minute, inspect the embedded unlock timestamp, or decrypt once the key is public. ## Default workflow 1. Choose a future UTC minute within the service's roughly 30-day certificate window, then encrypt with the bundled wrapper. Replace the timestamp placeholder: ```bash python3 skills/timelock-sh/scripts/timelock.py encrypt \ --unlock YYYY-MM-DDTHH:MMZ \ --input /absolute/path/to/plaintext.txt ``` 2. For non-text payloads such as archives, images, or other opaque files, use the same wrapper flow. The wrapper already adds the required OpenSSL `-binary` mode: ```bash python3 skills/timelock-sh/scripts/timelock.py encrypt \ --unlock YYYY-MM-DDTHH:MMZ \ --input /absolute/path/to/archive.tar.gz ``` 3. Read the JSON result: - `unlock_minute` is normalized to UTC minute form `YYYY-MM-DDTHH:MMZ`. - `output_path` is the generated CMS ciphertext, defaulting to `<input>.enc`. 4. If the user wants to inspect an existing ciphertext before decrypting it, extract the embedded unlock minute: ```bash …

How to install
mdr add brenorb/freedom-skills/timelock-sh@sha256:bdda9e2de10f6ddeThe line at the top of this page pins the label git:20261019.ecabd70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
