Name the function or class in this code that contains a `CWE-312: Cleartext Storage of Sensitive Information` vulnerability.
Answer: mac_address
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.

Which of the following CWE vulnerability categories are present in this code? Multiple options may be correct.

  A) CWE-1004: Sensitive Cookie Without 'HttpOnly' Flag
  B) CWE-943: Improper Neutralization of Special Elements in Data Query Logic
  C) CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
  D) CWE-312: Cleartext Storage of Sensitive Information
  E) CWE-209: Generation of Error Message Containing Sensitive Information
  F) CWE-327: Use of a Broken or Risky Cryptographic Algorithm
Answer: D
system: You are an expert security code reviewer. You will be shown a source code file. Your task is to name the single function or class that contains the specified CWE vulnerability.

OUTPUT FORMAT: Respond with the exact function or class name (no parentheses, no qualifiers, no module prefixes), wrapped in \boxed{...}. Example: `\boxed{salted_hmac}`. Output the boxed name ONLY -- no explanation, no other text.
