Rails: ActiveSupport::MessageEncryptor::InvalidMessage

Question

Help me please, I've finished 11 chapters of the rails tutorial, deployed my app to heroku (locally it worked perfectly) and it crashing all time. I'm using rails 5.2.2 After execution of command $heroku run rails console I'm receiving this:

Also, I've read this topic Running a rails server in production locally (InvalidMessage error) and haven't found files master.key and credentials.yml.enc on my PC.

Answer 1

Here are the docs for environmental security on rails https://guides.rubyonrails.org/security.html#environmental-security

In your case, you should have these files

config/master.key
config/credentials.yml.enc

Delete those files and then you can generate them with this:

rails credentials:edit --wait

While the credentials are open, note the master.key string, and then close the editor.

If you have not set the editor, you may need to do

EDITOR="your_editor_name --wait" bin/rails credentials:edit

The file master.key should be ignored by your version control because it is the key rails uses to decrypt the .enc, just commit your credentials.yml.enc and push it to heroku.

For master.key on heroku you can define the environment variable RAILS_MASTER_KEY on your heroku app and set it to the value of master.key.

Now to access the environments variables that you defined on your .enc file you must access them through Rails.application.credentials

ActionMailer::Base.smtp_settings = {
    :address        => 'smtp.sendgrid.net',
    :port           => '587',
    :authentication => :plain,
    :user_name      => Rails.application.credentials.SENDGRID_USERNAME,
    :password       => Rails.application.credentials.SENDGRID_PASSWORD,
    :domain         => 'heroku.com',
    :enable_starttls_auto => true
}

Answer 2

1. Remove the credentials:

rm -rf config/credentials.yml.enc

2. Create a new credentials:

  EDITOR="mate --wait" bin/rails credentials:edit

Hope it's helpful.

Answer 3

For me, it was because the environmental variable (found in the Heroku Settings page in the 'Config Vars' section) held an outdated master key.

Starting with Rails 6, you can have credentials per environment. So, I had credentials for production that differed from those in development; and both of these credentials have their own master key.

The one found here: config/master.key, is for the standard credentials file: config/credentials.yml.enc. The credentials file for production found here: config/credentials/production.yml.enc is encrypted with the production.key found in the same folder here: config/credentials/production.key.

I updated the key in Heroku in the Config Vars to the new production.key and everything deployed correctly.

I hope that this helps. Happy Coding!

*Also, I would recommend, after updating any Config Vars, to restart your dynos on Heroku. This insures that any new environmental variables are taken into account.

To do this, click on the 'More' button in the top right of any page, and then click on 'Restart all dynos'.

Answer 4

the only way for me was to renew my master key.

1. copy your decrypted credentials
2. remove the files
3. regenerate key
4. read the datas

This post help me https://github.com/rails/rails/issues/32718

Answer 5

I had this issue when working on a Rails 6 application in Ubuntu 20.04.

The issue was that I was setting/specifying a wrong RAILS_MASTER_KEY environment variable in my .env files in development (.env, .env.development). I just wanted to use it as a placeholder temporarily since I did not need it in my development environment.

This was then throwing the error below when I run a rails command, say rails generate uploader ProductImage:

`rescue in _decrypt': ActiveSupport::MessageEncry ptor::InvalidMessage (ActiveSupport::MessageEncryptor::InvalidMessage)

And even when I try generating a new master.key and the credentials.yml.enc files using rails credentials:edit or EDITOR="code --wait" bin/rails credentials:edit it throws the error below:

key=': key must be 16 bytes (ArgumentError)

Here's how to fix it:

What you have to do is to either provide the correct RAILS_MASTER_KEY environment variable in the .env file(s) or comment out the RAILS_MASTER_KEY environment variable if you are not using it.

That's it.

I hope this helps

Answer 6

I also faced the same problems a few moments later. Also, find a solution for me! basically, I'm using an android device for developing a Ruby on Rails app. the solution is: go to the app config directory. Then backup and remove the following files:

master.key
credentials.yml.enc

then go to terminal or on android, go to termux and write the command on app directory (must check you are on the rails app directory):

$ EDITOR=nano rails credentials:edit

you can also use other editors like Atom on desktops. now a new master.key and temporary non-encrypted credentials file will be created in terminal or termux (for android users). then press "ctrl+x" then "y" And then press enter, then the temporary non-encrypted credential file will be encrypted. now try to do your work. Now you might get a successful output. That's all. Happy Coding.

Notes: some points I get help for writing this answer from: https://github.com/rails/rails/issues/32718

Answer 7

1 Delete this 2 files:

config/master.key
config/credentials.yml.enc

2 Run this command:

EDITOR="nano" bundle exec rails credentials:edit

Answer 8

You need to ask for the master key to you project leader / team leader / coworkers.

With that long key like 3823729sdad29323832idsd you copy it and paste it the master.key file under config folder.

That solve the issue.

Answer 9

I have the same issue today, I found that I merge new credentials.yml.enc, so I tried to open EDITOR="code . --wait" rails credentials:edit getting the error listed here.

The solution for me was only deleting that extra empty line in the end of the file, that line was added after merging branches with vs code.

Answer 10

All my credentials were set properly, but I had forgot to set the master key in heroku.

How to set the master key on heroku

Go to /config/master.key, copy/paste the master key from the file then set it like so:

heroku config:set RAILS_MASTER_KEY=c9102a13496fdc09430445a6602e3j85

Answer 11

delete this file in config/credentials.yml.enc and create a new one using EDITOR="mate --wait" bin/rails credentials:edit
