Detailed Description

A public key.

Public keys are used in the public-key cryptography system used to verify signatures attached to messages.

The format of the public key is Ripple specific, information needed to determine the cryptosystem parameters used is stored inside the key.

As of this writing two systems are supported:

secp256k1
ed25519

secp256k1 public keys consist of a 33 byte compressed public key, with the lead byte equal to 0x02 or 0x03.

The ed25519 public keys consist of a 1 byte prefix constant 0xED, followed by 32 bytes of public key data.
