system: You are an expert security code reviewer. You will be shown a source code file along with a multi-select question listing several CWE (Common Weakness Enumeration) categories. Your task is to identify which of the listed CWEs are present in the code.

OUTPUT FORMAT: Respond with the letter(s) of all correct options, sorted alphabetically and comma-separated, wrapped in a single \boxed{...}. Examples: `\boxed{A}` for one correct, `\boxed{A,C}` for two, `\boxed{A,C,E}` for three. Output the boxed answer ONLY -- no explanation, no other text.

# Start with: python SSLPiclient_V1_1.py -s localhost -p 10023 -c ../Cert/server.pem
#        python SSLPiclient_V1_1.py -s ineltro-halmer.firewall-gateway.net -p 10023 -c ../Cert/server.pem

#Test Client for SSLPi 
# you can use it and modify it to your own needs. 
# It is tested to work together with SSLPi Server.
