Thank you for your pull request and welcome to our community. We could not parse the GitHub identity of the following contributors: jatZama.
This is most likely caused by a git client misconfiguration; please make sure to:

1. check if your git client is configured with an email to sign commits git config --list | grep email
2. If not, set it up using git config --global user.email [email protected]
3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails

Sorry I don't understand your point. I noticed the implementation of createEncryptedInput has as an optional argument the delegatedAccount argument already so I wanted to use same name in the type definition to avoid confusion.

Sorry I thought it was for encrypt. All good.
