Must specify an iv when adding form field

[dessery85]

Hi

I have just started to use this gem to encrypt email addresses in our database. I have created a script to programatically convert values from an existing email column to a new encrypted email_address column and this works fine, both encrypting and decrypting. I am now trying to update my views to output form inputs for the new column but when i do I get the follow error:

Must specify an iv

The code I am using is:

<div class="input-field"> <%= f.label :email_address, 'Contact Email:' %> <%= f.input :email_address, label: false, :wrapper => false %> </div>

Should this work? Or do I have to just add a field with a different field name using attr_accessor on my model, then programatically save that value to my email_address property on save? I couldn't see any examples on how best to approach this.

Any guidance would be greatly appreciated!!

Many thanks

I'm getting the same error randomly when processing encrypted values within the code (read only).
It looks like it has started happening after migrating to version 3.1.0

@dessery85 what does your schema for that object look like?

[szymonbaranowski]

Downgraded the gem to version 3.0.3, no Must specify an iv errors present since then (around 30 errors a day when using 3.1.0 during usual load). However, it looks to me like those have been replaced by the Cipher errors, same as in #207).

Yet another update from my side: I was able to reproduce the situation in the development environment by triggering multiple, heavy read-write operations on the AR objects using encrypted attributes. I also investigated production logs and there is a strong correlation between the occurrence of the Must specify an iv error and multiple simultaneous read-write operations on the AR objects.

@szymonbaranowski This PR looks like it could be addressing the same issue you're talking about: #320

Same Error for my form

<%= form_with model: @customer, url: '/add_key' do |form| %>
  <%= form.label "API Key" %>
  <%= form.text_field(:apikey) %>
  <%= form.submit %>
<% end %>
