Confusing configuration messaging

[samnissen]

When using symmetric-encryption, it warns of a missing config:

$ rake db:create # or whatever
# ...
Symmetric Encryption config not found.
To generate one for the first time: bin/rails generate symmetric_encryption:config

Taken at its word, this command does not complete the task, and generates an infinite loop unless carefully parsed:

$ rails generate symmetric_encryption:config

Symmetric Encryption config not found.
To generate one for the first time: bin/rails generate symmetric_encryption:config

Usage:
  rails generate symmetric_encryption:config KEY_PATH [options]

Runtime options:
  -f, [--force]                    # Overwrite files that already exist
  -p, [--pretend], [--no-pretend]  # Run but do not make any changes
  -q, [--quiet], [--no-quiet]      # Suppress status output
  -s, [--skip], [--no-skip]        # Skip files that already exist

Creates a SymmetricEncryption configuration file at config/symmetric-encryption.yml

I understand from the documentation here that my original command is missing the key path, and adding it successfully creates the config. I admit this is in the Usage section. However, I always forget this and find it confusing when initializing a new project.

Also, even successfully creating the config also triggers the message.

$ rails generate symmetric_encryption:config /path/to/keys

Symmetric Encryption config not found.
To generate one for the first time: bin/rails generate symmetric_encryption:config

      create  config/symmetric-encryption.yml

I suggest two changes

1. The error message changes from

Symmetric Encryption config not found.
To generate one for the first time: bin/rails generate symmetric_encryption:config

to

Symmetric Encryption config not found.
To generate one for the first time: 
1) `rails generate symmetric_encryption:new_keys development`
2) `bin/rails generate symmetric_encryption:config /path/to/keys`

See more information about generating keys here

2. The error messaging be removed from successful creation of the config.

v4 of Symmetric Encryption is now at beta3 and includes an all new CLI that addresses the above issues.
