I have seen Arun signing his commits since last month using key DA53058DBE154BDFCBF16BAD4B542AF704F74516 while working with him in golang team.
For nm.debian.org, at 2022-03-22: For the past 2 years, I have worked with Arun Kumar Pariyar on Deepin-related packages within Debian pkg-deepin packaging team. For this past work, Arun Kumar Pariyar sent mails using the email address openarungeek@gmail.com which is the one they're using on nm.debian.org, and they signed their work and email using a GPG key with fingerprint DA53 058D BE15 4BDF CBF1 6BAD 4B54 2AF7 04F7 4516. I've made sure that they are able to decrypt encrypted messages sent to this key and that they're able to sign messages with the same key. Due to the long-term interactions we had, I'm convinced that Arun Kumar Pariyar as they present themselves on nm.debian.org is the rightful owner of both email openarungeek@gmail.com and GPG key DA53 058D BE15 4BDF CBF1 6BAD 4B54 2AF7 04F7 4516.
