Digital Signature

Digital signatures are cryptographic techniques used to verify the authenticity and integrity of digital messages, documents, or software. They offer a way to ensure that the sender of a message is who they claim to be and that the message has not been altered or tampered with since it was signed.

Companies often use digital signatures for various purposes, including:

Document Authentication: Digital signatures are used to authenticate digital documents, such as contracts, agreements, or certificates, ensuring that they have not been altered and that they come from a trusted source.

Data Integrity: Digital signatures provide assurance that the content of a document or message has not been modified since it was signed. Any alteration to the signed content would invalidate the signature.

Non-Repudiation: Digital signatures provide evidence that the signer cannot deny their involvement in creating or sending the signed message or document. This is important for legal and compliance purposes.

Secure Transactions: Digital signatures are used in electronic transactions, such as online banking or e-commerce, to ensure the authenticity of transactions and to protect against fraud.

Regulatory Compliance: In many industries, digital signatures are used to meet regulatory requirements for secure communication and document management, such as in healthcare (HIPAA) or finance (PCI-DSS).
