This library is a small wrapper around the pypa/cryptography library.
It offers convenience methods for encrypting and decrypting arbitrary payloads in both AES and RSA.
For use encrypting / decrypting payloads in Anvil, you can generate an RSA keypair from your organization's settings page.
Anvil provides easy APIs for all things paperwork.
- PDF filling API - fill out a PDF template with a web request and structured JSON data.
- PDF generation API - send markdown or HTML and Anvil will render it to a PDF.
- Etch E-sign with API - customizable, embeddable, e-signature platform with an API to control the signing process end-to-end.
- Anvil Workflows (w/ API) - Webforms + PDF + E-sign with a powerful no-code builder. Easily collect structured data, generate PDFs, and request signatures.
Learn more about Anvil on our Anvil developer page.
- Python 3.7+
Install it directly into an activated virtual environment:
$ pip install python-anvil-encryption
or add it to your Poetry project:
$ poetry add python-anvil-encryption
This usage example is also in a runnable form in the examples/ directory.
