What is the key scheme and encoding used in GUN?

What are the key schemes, sizes, and encodings used in GUN db?

I didn't find a quick answer on searching so am adding the question here.

The keys look like:

let lee = await SEA.pair()
>lee.pub

"wfcQUDB44NhKFikH4NhWKVZfhQY-xGRpwnZIHjgmwRI.xLxhMgWvgvYHCc95L6Ni2RLmjJCMowWNbR3eQ1r4MOU"

Solution

  • For Signing/Verifying:

    Gun uses ECDSA with the P-256 curve.

    The keys are encoded in base64.

    More specifically, the public key is a . delineated concatenation of the x and y output parameters from running exportKey on a JSON web key (JWK) CryptoKeyPair object obtained from the subtleCrypto.exportKey function (following key generation using subtleCrypto.generateKey with ECDSA P256 curve).

    This has an overview of the x and y params.

    For Encryption/Decryption:

    Gun uses ECDH P-256 cruve with same process as above (public keys stored as lee.epub for OP example)
