Have you ever sent a message that you wished you could take back a few hours or days later? Wickr won’t exactly let you do that (I think few, if any, apps actually allow you to delete a message before it’s been read), but it will allow you to send encrypted messages that expire within a certain time period once they’ve been opened.
Aside from text messages, you’ll be able to send pictures, videos, PDFs, and voice messages with an extra layer of security so that only the message’s intended recipient will be able to read or access it.
Wickr flips messaging on its head, giving control to the sender instead of the receiver (or servers in between). Wickr uses AES256 to protect data and ECDH521 for the key exchange. RSA4096 is also used as a backup and for legacy app versions. Wickr also uses multiple rounds of SHA256 for hashing and Transport Layer Security (TLS).
With Wickr, messages are controlled (with the sender deciding who sees the contents of the message, for how long), private, encrypted, and anonymous. The only requirement is that the recipient has the app installed, too.
