Signature Verification Algorithms

Signature verification algorithms are methods used to confirm the authenticity of a digital signature, which is a unique code attached to a document to prove it comes from a specific person and hasn’t been altered. When someone signs a document digitally, the algorithm creates a signature using a private key (a secret code). To verify it, the algorithm uses a corresponding public key (a shared code) to check whether the signature matches the document. If it does, it assures that the signature is valid and the document is trustworthy. This process is crucial for secure communications and transactions online.
