![]() ![]() The Finished message will immediately follow the change cipher spec message. If Diffie-Hellman is used, the Diffie-Hellman parameters are transmitted to allow both client and server to generate the same pre-master secret.Īfter that, both sides will generate a master secret using the pre-master secret and the master secret will be used to generate the symmetric key for encrypting the session dataĪfter successful authentication and generating the pre-master secrets/master secrets, a change cipher spec message will be sent by both client and server indicating that the rest of the communication will be encrypted. Only the server will have the corresponding private key to decrypt and get the client generated pre-master secret. The client encrypts the pre-master secret by the public key of the certificate and sends to the server. If RSA is used as the key exchange algorithm, the client generates a 48-byte pre-master secret. There are two client key exchange methods described in the TLS v1.2 spec. ![]() The purpose of this message is to generate that common key between that client and the server without exposing to an outsider. In order to use symmetric encryption, there needs to be a common key between the two ends. Symmetric encryption is being used for this purpose as the computational cost is much lower than Asymmetric encryption. ![]() If the client certificate is not being presented (in one-way SSL), the client key exchange message should be sent after the client receives the ServerHelloDone message.Īs we all know the data transferred between the server and the client in an HTTPS connection will be encrypted. This message needs to be sent by the client following the Client Certificate message. The client will send the information that will be required by the server to start an HTTPS connection. Two-way SSL is mostly used in server to server communication where both parties need to validate the identity of each other.ĭuring an SSL handshake, the server and the client follow the below set of steps. Usually, when we browse an HTTPS website, one-way SSL is being used where only our browser (client) validates the identity of the website (server). ![]() The difference between those two is that in one -way SSL, only the client validates the identity of the server whereas in two-way SSL, both server and client validate the identity of each other. There are two types of SSL handshakes described as one-way SSL and two-way SSL (Mutual SSL). During the Handshake, server and client will exchange important information required to establish a secure connection. The main purpose of an SSL handshake is to provide privacy and data integrity for communication between a server and a client. Even though might not notice it, the browser and the website is creating an HTTPS connection using one-way SSL handshake. And also make sure you’ve granted USB access from the notification bar to be able to transfer the files.If you have ever browsed an HTTPS URL through a browser, you have experienced the SSL handshake. Make sure you uninstall Android File Transfer to prevent any errors. Once you install the app, you can just plug-in your device and you’re good to go. this app has beautiful native Mac UI, unlike Google’s boring and dull interface. Search the AppStore for HandShaker and install it. HandShaker has more features and support batch transfers over 4GB that Google’s tool doesn’t. If you do not like how Android File Transfer works, there is an alternative with no transfer limit. So you’ll have to drag and drop multiple times to transfer everything you want to. If you try to transfer files that goes above the 4GB limit, the app with probably freeze and stop responding. Note that the maximum size of transfer at a time is only 4GB. You can also click and drag the files you want to transfer. Select the files you want to transfer.Double click to open Android File Transfer.Using a USB cable, connect your device to the computer.Drag the Android logo to your Applications folder located on the right side.To start, download Android File Transfer from. Google has provided us with their own tool to help us transfer any file to Mac. How to Transfer Files from Android to Mac ![]()
