Digital signatures are a secure and reliable way to sign PDF documents electronically. A digital signature is a mathematical code created by a private key that belongs to the signer. When the signature is applied, it becomes a secure and unique representation of the signer’s identity that verifies the authenticity of the document.

For a digital signature to be legally valid, it must meet the following requirements:

• Authenticity: The signature must belong to a specific person and cannot be forged or tampered with.
• Integrity: The document must not be altered after the signature has been applied.
• Non-repudiation: The signer cannot deny their signature’s authenticity.
• Compatibility: The signature must be compatible with the PDF software used.

Digital signatures are legally valid in most countries and are accepted in most industries, including finance, healthcare, and government agencies. They offer several benefits, including reducing processing times, eliminating paper usage, and improving security and accessibility.
