js-libp2p-crypto
Crypto primitives for libp2p in JavaScript
This repo contains the JavaScript implementation of the crypto primitives needed for libp2p. This is based on this go implementation.
Table of Contents
Install
npm install --save libp2p-crypto
Usage
Example
const crypto = require('libp2p-crypto')
var keyPair = crypto.generateKeyPair('RSA', 2048)
API
generateKeyPair(type, bits)
type: String
, only'RSA'
is currently supportedbits: Number
Generates a keypair of the given type and bitsize.
generateEphemeralKeyPair(curve)
curve: String
, one of'P-256'
,'P-384'
,'P-521'
is currently supported
Generates an ephemeral public key and returns a function that will compute the shared secret key.
Focuses only on ECDH now, but can be made more general in the future.
Returns an object of the form
{
key: Buffer,
genSharedKey: Function
}
keyStretcher(cipherType, hashType, secret)
cipherType: String
, one of'AES-128'
,'AES-256'
,'Blowfish'
hashType: String
, one of'SHA1'
,SHA256
,SHA512
secret: Buffer
Generates a set of keys for each party by stretching the shared key.
Returns an object of the form
{
k1: {
iv: Buffer,
cipherKey: Buffer,
macKey: Buffer
},
k2: {
iv: Buffer,
cipherKey: Buffer,
macKey: Buffer
}
}
marshalPublicKey(key[, type])
key: crypto.rsa.RsaPublicKey
type: String
, only'RSA'
is currently supported
Converts a public key object into a protobuf serialized public key.
unmarshalPublicKey(buf)
buf: Buffer
Converts a protobuf serialized public key into its representative object.
marshalPrivateKey(key[, type])
key: crypto.rsa.RsaPrivateKey
type: String
, only'RSA'
is currently supported
Converts a private key object into a protobuf serialized private key.
unmarshalPrivateKey(buf)
buf: Buffer
Converts a protobuf serialized private key into its representative object.
