# Memona signature plugin

[md-ens-signature](https://github.com/capsulizers/md-ens-signature) library.
This version is the WebDAV folder alone; signing is not in it yet.
The plugin is a WASI component: it speaks no sockets of its own and makes every
request through the host's HTTP interface, under the connection's permissions.

## Signing
Saving a `.md` file holds it whole, up to 8 MiB, and writes it once finished,
with `signer` and `signature` set in its frontmatter; every other file streams
straight through. The signature is EIP-191 `personal_sign` over the signer name
and the body's SHA-256, made with the configured key; other frontmatter and the
body stay byte for byte. A key that is not 32 bytes of hex refuses the
connection, and a `.md` file that is not UTF-8 refuses the save. Reading passes
every file through unchanged. The RPC address is for verifying signers, which a
later version adds to reads.
