Dsa Public Key

Now that you have created a public key and a private key, you are ready to sign the data. In this example you will sign the data contained in a file. GenSig gets the file name from the command line. A digital signature is created (or verified) using an instance of the Signature class.

Signing data, generating a digital signature for that data, is done with the following steps.

Get a Signature Object: The following gets a Signature object for generating or verifying signatures using the DSA algorithm, the same algorithm for which the program generated keys in the previous step, Generate Public and Private Keys.

Note: When specifying the signature algorithm name, you should also include the name of the message digest algorithm used by the signature algorithm. SHA1withDSA is a way of specifying the DSA signature algorithm, using the SHA-1 message digest algorithm.

Feb 02, 2013 Java Code for RSA Key Generation. // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Dsa dsa = new Chilkat.Dsa ; // Call GenKey to generate a new DSA key. // The number of bits should be at least 1024 and a multiple // of 64. Typical values are either 1024 or 2048.

∟ DSA Private Key and Public Key Pair Sample. This section provides a tutorial example on how to run JcaKeyPair.java to generate a DSA private key and public key pair sample. Keys are stored PKCS#8 and X.509 encoding formats.  Here is the result of my first test of JcaKeyPair.java - generating a pair of DSA private key and public key.

Before a Signature object can be used for signing or verifying, it must be initialized. The initialization method for signing requires a private key. Use the private key placed into the PrivateKey object named priv in the previous step.

Supply the Signature Object the Data to Be Signed This program will use the data from the file whose name is specified as the first (and only) command line argument. The program will read in the data a buffer at a time and will supply it to the Signature object by calling the update method.
