Your Facebook Pokes Are Stored For Two Days, Then Their Encryption Keys Are Deleted

Facebook Poke messages self-destruct after a few seconds. but is Facebook saving these potentially embarrassing photos and videos? No. It's deleting them. Pokes are encrypted, and Facebook deletes the encryption keys two days after they're read so they're unreadable. Key backups are destroyed within 90 days, making a poke completely inaccessible. So send those silly, racy messages with confidence.
