end-to-end Encryption Process

1. ID Generation

   • Unique random ID created for each link (e.g. R53nSAg)
   • Example: google.com → tnyr.me/R53nSAg

2. Hashing

   • Two Argon2 hashes are calculated by using different salts

3. Storage

   • Original URL encrypted with AES-256-GCM using Hash 2
   • Only Hash 1 (storage key) is saved in database
