If you have data for which a digital signature was generated, you can verify the authenticity of the signature. To do so, you need the data the signature the public key corresponding to the private key used to sign the data In this example you write a VerSig program to verify the ...
The Signature class is used to provide applications the functionality of a digital signature algorithm. Digital signatures are used for authentication and integrity assurance of digital data. The signature algorithm can be, among others, the NIST standard DSA, using DSA and SHA-1. The DSA algorithm...
