Surespot

Send encrypted text messages

Use surespot and everything you send can only be read by the person you sent it to. Period. Everything sent using surespot is end-to-end encrypted with symmetric-key encryption (256 bit AES-GCM) using keys created with 521 bit ECDH shared secret derivation, but you wont notice because security in surespot is built-in, not a layer over something else. Be confident sending private information and pictures, you have control over your messages, when you delete a sent message it will be removed from the receiver's phone and images are not shareable unless you make them so. Multiple identities allow you to be who you want with just who you want, and if anyone gets annoying you can block them. Surespot does not require or store your phone number or email address and we don't mine your data, no advertisements here!
