Google Pay Token Decryption (Rust Implementation) 🔐

A Rust implementation for decrypting and verifying Google Pay payment tokens according to Google's encryption specifications.

📱 About Google Pay & Tokenization

Google Pay is a digital wallet platform that enables users to:

• Store payment methods securely
• Make contactless payments
• Complete in-app/online purchases

Tokenization is the security process that:

1. Replaces sensitive card details with a unique token
2. This token is worthless if intercepted
3. The actual payment details never touch merchant servers
