default_keylog_callback(connection, key_material)

Callback function to handle logging of TLS key material.

This function is called whenever TLS key material is generated or received. It writes the key material to a log file and updates a dictionary with the key material for each recognized label.

Parameters:

• connection (SSL.Connection) – The SSL/TLS connection object associated with the key material.

• key_material (bytes) – The key material to log, which includes the label and associated key.

Returns:

None

log_key_material_dict()

Log the contents of the key material dictionary.

This function prints each label and the associated key material stored in the key_material_dict. It helps in debugging and verifying the key material collected during the TLS sessions.
