Encryption is based on the mathematical scrambling and unscrambling of messages. The type of encryption we use assigns two keys -- one is a public key and one is a private key. When you send us a message, you use our public key to encrypt your message. Once we receive your encrypted message, we use the private key to decode it. The same key cannot both encrypt and decrypt information. So, information encrypted using the private key can only be decrypted using the public key, and vice versa -- ensuring the security of your information.
