Which of the following formats is used specifically for secure file transfers in SFTP?

• A. PEM format
• B. XML format
• C. JSON format
• D. DOC format

Answer: (A)

The correct choice refers to the PEM format, which stands for Privacy Enhanced Mail. This format is particularly relevant in the context of secure file transfers, including those utilizing SFTP (Secure File Transfer Protocol). PEM is primarily used for encoding cryptographic keys and certificates, which are critical for establishing secure connections. In SFTP, a secure channel is required for transferring sensitive data, and the underlying security often relies on encryption protocols which utilize keys and certificates. PEM format enables the storage and transmission of these keys in a structured, text-based format that is both human-readable and can be easily processed by software. The other formats listed—XML, JSON, and DOC—serve different purposes. XML and JSON are both markup and data interchange formats, respectively, mainly used for structuring data, whereas DOC is a word processing format. These formats do not inherently have the function of supporting secure file transfers or encryption, making them unsuitable in this context. Thus, PEM format stands out as the specific choice that aligns with the requirements of secure file transfer protocols like SFTP.
