Thanks to React hooks you have now happily turned all your classes into functional components.
Wait, all your components? Not quite. There is one thing that can still only be implemented using classes: Error boundaries.
There is just no functional equivalent for componentDidCatch and deriveStateFromError yet.

| `openssl pkcs12 -in [yourfile.pfx] -nocerts -out [keyfile-encrypted.key]` | |
| What this command does is extract the private key from the .pfx file. Once entered you need to type in the importpassword of the .pfx file. This is the password that you used to protect your keypair when you created your .pfx file. If you cannot remember it anymore you can just throw your .pfx file away, cause you won’t be able to import it again, anywhere!. Once you entered the import password OpenSSL requests you to type in another password, twice!. This new password will protect your .key file. | |
| Now let’s extract the certificate: | |
| `openssl pkcs12 -in [yourfile.pfx] -clcerts -nokeys -out [certificate.crt]` |
| require 'aws/s3' # gem name is 'aws-sdk' | |
| class BucketSyncService | |
| attr_reader :from_bucket, :to_bucket, :logger | |
| attr_accessor :debug | |
| DEFAULT_ACL = :public_read | |
| # from_credentials and to_credentials are both hashes with these keys: | |
| # * :aws_access_key_id |
