## Message

```
crypto.sign.ed25519: add support for blind key signatures (#11868)

Key blinding allows public keys to be augmented with a secret
scalar, making multiple signatures from the same signer unlinkable.

https://datatracker.ietf.org/doc/draft-dew-cfrg-signature-key-blinding/

This is required by privacy-preserving applications such as Tor
onion services and the PrivacyPass protocol.
