Why Your API Should Use Delta Encryption

from The Developer Tools Podcast with Fexingo: APIs, Infrastructure, and Software for Engineers Hosted by Fexingo

Every webhook you ship is a plaintext postcard. In this episode, Lucas and Luna dig into delta encryption — the practice of encrypting individual fields or events in your API payloads rather than wrapping the whole thing in TLS and calling it a day. They walk through a real example: a fintech that accidentally leaked customer names because their webhook payloads were signed but not encrypted. They explain how envelope encryption works, why it matters for compliance, and where it fits alongside transport security. If you've ever wondered whether your API is actually protecting sensitive data, or what 'end-to-end encrypted webhooks' really means, this one's for you. #DeltaEncryption #WebhookSecurity #APISecurity #EnvelopeEncryption #DataEncryption #Compliance #DeveloperTools #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #SoftwareEngineering #Infrastructure #TechPodcast #Encryption #API #Webhooks #Security #LucasAndLuna Keep every episode free: buymeacoffee.com/fexingo
