SignVerify

SignVerify is a cryptographic tool designed to ensure the authenticity and integrity of digital documents. It operates by using a pair of cryptographic keys: a private key for signing and a public key for verification. The private key is kept secret by the signer, while the public key can be freely distributed to anyone who needs to verify the signature.

The process begins with the signer generating a digital signature using their private key and the document's hash. This signature is then appended to the document. To verify the signature, the recipient uses the signer's public key to decrypt the signature and compare it with the hash of the received document. If the hashes match, the document is considered authentic and unaltered.

SignVerify is widely used in various applications, including software distribution, digital certificates, and secure communications. It provides a robust mechanism for verifying the origin and integrity of digital data, thereby enhancing security and trust in digital transactions.
