RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including iron-webcrypto. Try it out:
const { webcrypto } = require('node:crypto')
const Iron = require('iron-webcrypto')
const obj = {
a: 1,
b: 2,
c: [3, 4, 5],
d: {
e: 'f'
}
}
const password = 'a_password_having_at_least_32_chars'
const sealed = await Iron.seal(webcrypto, obj, password, Iron.defaults)
console.log({ sealed })
const unsealed = await Iron.unseal(webcrypto, sealed, password, Iron.defaults)
console.log({ unsealed })
