dac-keypairs   

An implementation of dac keypairs & wallet generation using
elliptic which supports rfc6979 and
eddsa deterministic signatures.

API Methods

``
generateSeed({entropy?: Array, algorithm?: string}) -> string
`
Generate a seed that can be used to generate keypairs. Entropy can be provided as an array of bytes expressed as integers in the range 0-255. If provided, it must be at least 16 bytes long. If not provided, entropy will be automatically generated. The "algorithm" defaults to "ecdsa-secp256k1", but can also be set to "ed25519". The result is a seed encoded in base58, starting with "s".

`
deriveKeypair(seed: string) -> {privateKey: string, publicKey: string}
`
Derive a public and private key from a seed. The keys are represented as 33-byte hexadecimal strings.

`
sign(messageHex: string, privateKey: string) -> string
`
Sign an arbitrary hex-encoded message with a private key. Returns the signature as a hexadecimal string.

`
verify(messageHex: string, signature: string, publicKey: string) -> boolean
`
Verify a signature for a given hex-encoded message and public key. Returns true if the signature is valid, false otherwise.

`
deriveAddress(publicKey: string) -> string
`
Derive a dac address from a public key.

`
deriveNodeAddress(publicKey: string) -> string
`
Derive a node address from a public key.

Generate a random dac address

`
const seed = generateSeed();
const keypair = deriveKeypair(seed);
const address = deriveAddress(keypair.publicKey);
