New Encryption Feature 🔑🔐

This release introduces encryption functionality which will automatically encrypt/decrypt your credential secrets when in use with the IGM tool.

• The credential secrets file .env is automatically encrypted and decrypted automatically when editing/view or interaction with the IGM tool.
• Encryption key is automatically deleted after decryption to ensure a new key is generated each after encryption.
• Key is stored alongside the encrypted file, matching the alias for easy identification. If key is deleted or lost then file can't be decrypted.
• Encryption functionality is also extended to backup & restore feature.
• Everything looks and feels the same when you view/edit/interact with the credential secrets via the tool due to auto-decryption. If trying to inspect the file outside of the tool, it will stay encrypted.

ℹ️ As always, update the tool, then launch IGM after the update. Your credential file will be automatically encrypted over once you've interacted with the tool.
