Hey @Srikrishnasiddala, there has been some issue actually. There were a couple of duplicate issues, this was one of them. Apologies for the inconvenience caused, there already exists an entry for b2a_hex(), so I'll have to close this PR for now. You can take up another issue for contribution. Thank you! 😄
