What is the digital signature in pdf

A digital signature in PDF is a cryptographic method used to verify the authenticity and integrity of a document. It ensures that the document has not been altered after signing and confirms the identity of the signer. This type of signature is legally recognized in the United States, making it suitable for various applications, including contracts, agreements, and forms.

Digital signatures utilize public key infrastructure (PKI) technology, which involves a pair of keys: a private key, known only to the signer, and a public key, which is accessible to anyone. When a document is signed digitally, a unique hash of the document is created and encrypted with the signer's private key. This process allows recipients to verify the signature using the corresponding public key.

Legal use of the digital signature in pdf

In the United States, digital signatures are legally binding under the Electronic Signatures in Global and National Commerce (ESIGN) Act and the Uniform Electronic Transactions Act (UETA).

• Be uniquely linked to the signer.
• Be capable of identifying the signer.
• Be created using a method that is under the sole control of the signer.
• Be linked to the document in a way that any changes to the document are detectable.

Understanding these legal frameworks helps users navigate the requirements for using digital signatures effectively.
