Encryption key FAQ

Securely sharing encryption keys.

Never share the link to an encrypted file and the encryption key using the same transmission mechanism.

For example, email the link to a file, and then send the encryption key by text message, never send the file and encryption key by email.

Creating secure passwords / encryption keys.

  • Always create long, random encryption keys. For example, 20 characters, with a random combination of lowercase and uppercase alphanumeric and symbols.
  • Never re-use encryption keys
