ASDF (Authenticated Signatures in Digital Formats)

ASDF (Authenticated Signatures in Digital Formats) is a standard for securely signing and verifying digital files. It ensures that a document or data has not been altered and truly comes from the claimed sender. Using cryptographic techniques, ASDF embeds a digital signature into the file, allowing recipients to confirm its authenticity and integrity. This is especially useful for sensitive or official documents, providing trust that the information is genuine and unchanged during transmission or storage.
