Reverse Engineering TicketMaster's Rotating Barcodes (SafeTix)
TicketMaster's barcodes contain a SHA-1 TOTP generated with an eventKey, customerKey, and Unix timestamp. The author extracts these values to replicate the barcodes in a custom app or resell tickets outside of TicketMaster's marketplace. The base64 token string is the ticket itself, allowing valid PDF417 barcodes to be generated.
