// Package sign signs small messages using public-key cryptography.
//
// Sign uses Ed25519 to sign messages. The length of messages is not hidden.
// Messages should be small because:
// 1. The whole message needs to be held in memory to be processed.
// 2. Using large messages pressures implementations on small machines to process
// plaintext without verifying the signature. This is very dangerous, and this API
// discourages it, but a protocol that uses excessive message sizes might present
// some implementations with no other choice.
// 3. Performance may be improved by working with messages that fit into data caches.
// Thus large amounts of data should be chunked so that each message is small.
//
// This package is not interoperable with the current release of NaCl
// (https://nacl.cr.yp.to/sign.html), which does not support Ed25519 yet. However,
// it is compatible with the NaCl fork libsodium (https://www.libsodium.org), as well
// as TweetNaCl (https://tweetnacl.cr.yp.to/).
