The Internet is forever! Your private communications don’t need to be. Wickr®’s mission is to provide a free and easy way for anyone to send encrypted messages and Leave No Trace®.
Both sender and receiver must have the app to communicate. Only the receiver is able to decrypt the message once it was sent. Wickr® does not have the decryption keys.
Send and receive text, photos, videos, voice and pdfs that are::
We have made this app with the best available security technology, but we strongly encourage you to only send private messages to people you trust.
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.
Wickr® has hundreds of thousands of downloads in over 113 countries. Celebrities, royalty, reporters, feds, lawyers, doctors, investors and teens are the early adopters.
