Store encrypted data, and retrieve it decrypted using Meteor and Mongo

Question

I'm new to Meteor, I'm trying to build a simple application using Pup.

I have a collection Videos and I have a property url in this collection. I want to store the url encrypted in the database. I'm wondering what's the best way to do so? where exactly should I hook my encrypt/decrypt logic?

I set the encrypted value in the autoValue hook of simpleSchema as following:

url: {
  type: String,
  label: 'The url of the video.',
  autoValue() {
    return EncryptionHelper.encrypt(this.value);
  }
},

But can't find the place where I should decrypt it back.
