This should be encrypted by an asymmetric encryption method. This encryption method has two keys. One is the public key (as the name implies, this is a public key value) and the other is the private key (confidentiality). When you send us information, please use the public key to encrypt the information. Once we receive your encrypted information, we will use the private key to decrypt the information password (the information encrypted by our public key can only be decrypted by our unique private key, thus technically ensuring that only we can read this letter-because others don't have our private key). Information encrypted by private key can only be decrypted by public key (this function is applied to the field of digital signature, and only my public key can interpret the data encrypted by my private key, see the information of digital signature for details), and vice versa, to ensure your information security.

See Digital Signature /view/7626.htm for details.
