The client makes a hello request in frame 778 The server responds with its certificate and then continued bytes from the server certificate. The client then sends an "Encrypted handshake message" The client then sends its certificate with Client Key exchange and also indicates a change of cipher spec. In frame 917, we can see an encrypted alert!
Using Spec Files — PyInstaller 3.6 documentation the first thing PyInstaller does is to build a spec (specification) file myscript.spec.That file is stored in the --specpath= directory, by default the current directory.. The spec file tells PyInstaller how to process your script. It encodes the script names and most of the options you give to the pyinstaller command. The spec file is actually executable Python code. mod_ssl - Apache HTTP Server Version 2.4 The default cipher-spec string depends on the version of the OpenSSL libraries used. Let's suppose it is ``RC4-SHA:AES128-SHA:HIGH:MEDIUM:!aNULL:!MD5'' which means the following: Put RC4-SHA and AES128-SHA at the beginning. We do this, because these ciphers offer a good compromise between speed and security. Next, include high and medium
An important fact to note about change cipher spec message is that, "SSL alert messages are produced, when this ssl cipher spec message is used, other than the normal fashion". Rate this article: Select rating Give it 1/5 Give it 2/5 Give it 3/5 Give it 4/5 Give it 5/5

The client sends "Change cipher spec" notification to server to indicate that the client will start using the new session keys for hashing and encrypting messages. Client also sends "Client finished" message. Server receives "Change cipher spec" and switches its record layer security state to symmetric encryption using the session keys. Server
Grain-128AEAD is a bit oriented stream cipher and it thus also allows byte string inputs. The message padding of one ’1’ bit, can in an environment that only operates with bytes, be replaced by a ’1’ followed by seven ’0’s. This will not a ect the MAC result. 4 11. The purpose of the Change Cipher Spec record is to show that the subsequent SSL records sent by the client will be encrypted. The record is 6 bytes long. 12. In the encrypted handshake record, the session will generate a MAC of the concatenation that includes all the previous handshake messages sent from the client, and then send this concatenation to the server. The change cipher spec message, transmitted by both the client and the server, defines the re-negotiated cipher spec and keys that will be used for all the messages exchanged henceforth. The client sends a change cipher spec message following handshake key exchange and certificate verify messages (if any), and the server sends one after successfully processing the key exchange message it received from the client. An unexpected change cipher spec message should generate an unexpected_message alert (Section 5.4.2). When resuming The Change Cipher Spec record is used to indicate the content of the next SSL records will be encrypted. It is 6 bytes. 12. In the encrypted handshake record, what is being encrypted? How? Answer All handshake messages and MAC addresses are concatenated and encrypted. They are sent to the server. If you do Finished after change_cipher_spec, and since Finished has to be the first message after setting the cipher spec, you get the added benefit of requiring a successful decryption of a message before any (potentially sensitive) user data is transmitted. This step serves as an extra "checksum". The client makes a hello request in frame 778 The server responds with its certificate and then continued bytes from the server certificate. The client then sends an "Encrypted handshake message" The client then sends its certificate with Client Key exchange and also indicates a change of cipher spec.
