Proxy re-encryption (PRE) is a cryptographic method letting a third-party proxy convert a ciphertext from one user's key to another's, without the proxy seeing the original data, enabling secure, delegated access to encrypted information, widely used in cloud storage, secure messaging, and healthcare for sharing data without private keys, offering secure, dynamic access control

I came across this thread while recently searching for opinions on simplynode.io before making a purchase. I finally gave it a try and haven't regretted it yet. I use proxies mainly for social media and checking websites from different countries - I used to constantly encounter blocks and captchas, but this one is much better. I especially like the flexibility of session management and the freedom from a strict subscription.
