A digital signature on a PDF (Portable Document Format) certifies the signer’s identity and verifies that the document’s contents have not been altered since it was signed. For example, businesses commonly use digital signatures on contracts to maintain legal validity while operating remotely.
Digital signatures are crucial for preserving the integrity of documents and streamlining business processes. Historically, the concept of digital signatures emerged from public-key cryptography in the 1970s, enabling secure online transactions and document authentication.
