Supply it with the data whose signature is to be verified (from the file specified as the third command line argument), and verify the signature. Compile and Run the Progra The code example below clearly demonstrates the steps about how to verify digital signatures in an already signed PPS file in Java using GroupDocs.Signature library by adding just a few lines of code. Create new instance of Signature class and pass source document path as a constructor parameter Also, you must verify the default digital identity for signing on Tools->Sign and Certify->More Sign and Certify->Security Settings, if the correct digital ID is set by default (with the pen icon at left side of name).If not, select the correct ID with mouse and set as default, in Usage Options->Use for Signing Implementing Digital Signatures. Let us implement the digital signature using algorithms SHA and RSA and also verify if the hash matches with a public key. Approach: Create a method named Create_Digital_Signature() to implement Digital Signature by passing two parameters input message and the private key


Supply the Signature Object With the Data to be Verified You now need to supply the Signature object with the data for which a signature was generated. This data is in the file whose name was specified as the third command line argument. As you did when signing, read in the data one buffer at a time, and supply it to the Signature object by calling the update method You can sign a source document using the given CertificateHolder and SignOptions with the digital signature and writes the signed document to the destination file. Using SignOptions class you can specify options for document signing.
