@session.js/mnemonic

Mnemonic/seed phrase utilities for Session messenger. Seed hex (and thus random mnemonic and random Session ID) can be generated using @session.js/keypair.

encode (seed hex -> phrase)

To encode mnemonic:

import { encode } from '@session.js/mnemonic'

encode('39038c8988db02c1af44e8c847bd9713') // => 'puffin luxury annoyed rustled memoir faxed smidgen puddle kiwi nylon utopia zinger kiwi'

decode (phrase -> seed hex)

To decode mnemonic:

import { decode } from '@session.js/mnemonic'

decode('puffin luxury annoyed rustled memoir faxed smidgen puddle kiwi nylon utopia zinger kiwi') // => '39038c8988db02c1af44e8c847bd9713'

Example: Generate random Session ID

Install @session.js/keypair to generate random seed hex.

Hint: Session IDs are x25519 aka Curve25519 public keys prepended with 05

import { generateSeedHex, getKeypairFromSeed } from '@session.js/keypair'
import { encode } from '@session.js/mnemonic'

const seedHex = generateSeedHex()
const keypair = getKeypairFromSeed(seedHex)
const mnemonic = encode(seedHex)
const sessionID = keypair.x25519.publicKey

console.log('Generated session ID:', sessionID)
console.log('Mnemonic for it:', mnemonic)

Dictionaries

By default, this package comes only with english dictionary. You can add your own mnemonic languages:

import { decode, mnemonicLanguages, addMnemonicLanguage } from '@session.js/mnemonic'

mnemonicLanguages.russian = addMnemonicLanguage({
  prefixLen: 3,
  words: [/* ... */]
})
decode('любовь любовь любовь любовь любовь любовь любовь любовь любовь любовь любовь любовь любовь', 'russian')

Made for session.js

Use Session messenger programmatically with Session.js: Session bots, custom Session clients, and more.
