If a code signer does not yet have a suitable private key for signing the code, the key must first be generated, along with a corresponding public key that can be used by the code receiver's runtime system to verify the signature.
The simplest way to generate a key pair is to run ssh-keygen without arguments. In this case, it will prompt for the file in which to store keys. Here's an example: klar (11:39) ssh-keygen Generating public/private rsa key pair. My confusion, and this might be a little bit directly related to Java API., is that using GCM mode I can specify: a nonce, AAD data. So, my questions: Is the nonce used to generate a 'probabilistic ciphertext', as with IV in CBC mode? Is the nonce also used as key to generate the HMAC for the ciphertext? How to generate the correct oauthsignature in apex.Here is the code for generating oauthnonce, oauthtimestamp and oauthsignature. But not getting the correct oauthsignature. // Generate a unique combination of numbers and alphabets for oauth-nonce String nonce = String.valueOf(Crypto.getRandomLong); Blob key = Blob.valueOf(nonce).
Since this lesson assumes that you don't yet have such keys, you are going to create a keystore named
examplestore and create an entry with a newly generated public/private key pair (with the public key in a certificate).

Type the following command in your command window to create a keystore named
examplestore and to generate keys:
You will be prompted to enter passwords for the key and keystore.
Subparts of the keytool Command
Let's look at what each of the
keytool subparts mean.
Note: For security reasons you should not set your key or keystore passwords on the command line, because they can be intercepted more easily that way.
Distinguished-Name Information
If you use the preceding
keystore command, you will be prompted for your distinguished-name information. Following are the prompts; the bold indicates what you should type.
Command Results
The
keytool command creates the keystore named examplestore (if it doesn't already exist) in the same directory in which the command is executed. The command generates a public/private key pair for the entity whose distinguished name has a common name of Susan Jones and the organizational unit of Purchasing.
The command creates a self-signed certificate that includes the public key and the distinguished-name information. (The distinguished name you supply will be used as the 'subject' field in the certificate.) This certificate will be valid for 90 days, the default validity period if you don't specify a -validity option. The certificate is associated with the private key in a keystore entry referred to by the alias
signFiles .
Self-signed certificates are useful for developing and testing an application. However, users are warned that the application is signed with an untrusted certificate and asked if they want to run the application. To provide users with more confidence to run your application, use a certificate issued by a recognized certificate authority.
Note: The command could be shorter if option defaults are accepted or you wish to be prompted for various values. Whenever you execute a
keytool command, defaults are used for unspecified options that have default values, and you are prompted for any required values. For the genkey command, options with default values include alias (whose default is mykey ), validity (90 days), and keystore (the file named .keystore in your home directory). Required values include dname, storepass, and keypass.
Key generators are constructed using one of the
getInstance class methods of this class.
C# Nonce
KeyGenerator objects are reusable, i.e., after a key has been generated, the same KeyGenerator object can be re-used to generate further keys.
There are two ways to generate a key: in an algorithm-independent manner, and in an algorithm-specific manner. The only difference between the two is the initialization of the object:
In case the client does not explicitly initialize the KeyGenerator (via a call to an
init method), each provider must supply (and document) a default initialization.
Every implementation of the Java platform is required to support the following standard
KeyGenerator algorithms with the keysizes in parentheses:
