crypto functions in apigee javascript policy

[syborg78]

Hi,

What is the easiest way convert this nodejs code using the builtin crypto package into an Apigee policy (preferably javascript)

const crypto=require('crypto');
const value = "stringtohash";
const hash = crypto.createHash('sha256').update(value).digest('hex');
const salt = "somlargevaluerepresentingthesalt";
const pbkHash = crypto.pbkdf2Sync(value, salt, 100000, 32, 'sha256').toString('hex');

hash and pbkHash would be available as context variables for subsequent policies.

Thanks.
