Cryptographic key pairs for the XRP Ledger
npm install ripple-keypairsAn implementation of XRP Ledger keypairs & wallet generation using
elliptic which supports rfc6979 and
eddsa deterministic signatures.
``
generateSeed({entropy?: Array
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 16 bytes long (additional bytes are ignored). 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 an XRP Ledger classic address from a public key.
`
deriveNodeAddress(publicKey: string) -> string
Derive a node address from a public key.
`
const seed = generateSeed();
const keypair = deriveKeypair(seed);
const address = deriveAddress(keypair.publicKey);
