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

  A) CWE-327: Use of a Broken or Risky Cryptographic Algorithm
  B) CWE-326: Inadequate Encryption Strength
  C) CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
  D) CWE-943: Improper Neutralization of Special Elements in Data Query Logic
  E) CWE-117: Improper Output Neutralization for Logs
  F) CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Answer: A
system: You are an expert security code reviewer. You will be shown a source code file along with a multiple-choice question listing several function or class names from that file. Your task is to identify which one contains the specified CWE vulnerability.

OUTPUT FORMAT: Respond with the single letter of the correct option, wrapped in \boxed{...}. Example: `\boxed{B}`. Output the boxed letter ONLY -- no explanation, no other text.
