    The platform includes a wide range of sellers, and not all of them provide detailed information or ratings, which can make it difficult to assess seller reliability.

  • Reliance on Internet Access
    Users need an active internet connection to utilize the tool, which can be a limitation in areas with unreliable internet service.
  • Privacy Concerns
    While using an online service to decode certificates, there can always be privacy concerns regarding sensitive data being uploaded to a third-party server.
