Did you know? PGP messages are often too long to send easily to friends. But Si4Key has introduced a creative solution—PGP Message Relay. It uploads your encrypted message to the cloud and gives you a short link. You can then share this link with your friends, allowing them to access the content. Most importantly, you’re always in control—you can enable or disable this feature in settings. Also, the message stored in the cloud is temporary—usually kept for only one hour, which greatly improves security. You can easily send the short link via iMessage, making your conversations clear and concise.
