How to generate address directly from curve point

Developers Cardano Integration
1

Hello. According to my understanding cardano uses ed25519 for its asymmetric cryptography. I’m able to create a curve point via the elliptic npm package but I need to be able to convert it directly into a public address. If there are any (js) packages you could recommend to do so I’d be very grateful. I need to directly generate an address from a point as I need the public and private key to have specific properties.

I can’t seem to find the direct specification on how the different addresses are generated. Specifically the Daedalus-style address (DdzFF…) and Shelley era address (addr1…). I’m wondering if I should also support the older Icarus-style format (Ae2…). Another question I have is does ADA use shnorr or ecdsa for its signatures?

Any help would be much appreciated, thanks.

Hi!

Have you found this lib?

Haven’t found it yet, but it doesn’t seem to provide what I’m looking for, it assumes that I already have the public key in some specific format.

https://docs.cardano.org/projects/cardano-serialization-lib/en/latest/getting-started/generating-keys.html
I think this can be used to generate private and public address from recovery phrase.

See CIP1852 and “About Address Derivation” in the docs. That might answer your question.

Only seems to provide a spec for the old address format.

As I said I don’t want to generate an address from a mnemonic phrase but instead directly from a cryptographic point

The 1852 is what we’re currently using.
