Security is for Everyone

Whether personal or business, your conversations and data are private by design. You are in charge, always.

Wickr employs multiple layers of encryption to secure your data and messages, both at rest and in transit, including:
  • Wickr username, application ID and device ID are cryptographically hashed with multiple rounds of salted SHA256.
  • Data at rest and in transit is encrypted with AES256.
  • As part of Perfect Forward Secrecy, each message has a new encryption key that is deleted as soon as message is decrypted.
  • Message encryption keys are encrypted with a key produced using ECDHE.
  • Messages are bound to both the receiver’s application and device.
  • No password or password hashes ever leave user device.
  • All user content is forensically wiped from the device after it expires.
  • Your UDID (Unique Device Identifier) is never uploaded to our servers so you are always anonymous to us.

End-to-end Encryption

Content is encrypted locally on user devices and is only accessible to intended recipients. Wickr never has the decryption keys.

Ephemerality

No conversation lives beyond its useful life – you decide when your content gets automatically deleted for good.

Perfect Forward & Backward Secrecy

Every message, file and call is encrypted with a new random key. As of now, breaking just one key would take trillions of years to decipher.

Zero Knowledge

Even in the case of a breach, Wickr servers have no user communications - they are undecipherable in transit and deleted upon delivery.
