Re: [tor-dev] ed25519_master_id_public_key -> ed25519 id

Yes, there is!

First you verify that the file is really 64 bytes long, and that the first 32 bytes of the file are really "== ed25519v1-public: type0 ==\0\0\0".

Having done that, you base64-encode the second 32 bytes of the file, with no "=" padding.

thank you for this description, so I can confirm that this:

cut -b 33- ed25519_master_id_public_key |base64

gives me the same string as in the file fingerprint-ed25519

kind regards, nusenu
