Move aside Whatsapp and Snapchat , Wickr is a better,more secure messaging app for adults. The military grade encryption service from Wickr promises to leave no trace, while giving the sender the ability to send private text, images, audio, or videos to anyone. All messages automatically self-destruct within six days, or sooner if you want to change the default.
Co-founder Nico Sell, tells CNET, even “my 3-year-old can send encrypted messages” with Wickr. The app doesn’t collect information from you like your email. Just download it and you’re ready to send with a username and password of your choice. However, both sender and receiver must have the app to send/receive messages. Users can also opt to block other users.
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 SHA256 for hashing and Transport Layer Security (TLS). Encryption keys are used only once then destroyed by the sender’s phone. Each message is encrypted with its own unique key and no two users can have the same AES256 or ECDH521 keys ever. Our servers do not have the decryption keys, only the intended recipient(s) on the intended devices can decrypt the messages.
