Autodesk 3ds max 2014 product key generator. The same version of AutoCAD is in bothsoftware packages but the product key differentiates one packagefrom the other.Note:Please ensure you are using the correctproduct key for the Autodesk product and version you areinstalling. Product keys are required for installation of Autodesk productsand are used to differentiate products that are both soldindependently and as part of a product suite. For example,installing AutoCAD 2016 as a point product requires product key001H1, but installing AutoCAD 2016 from theAutodesk Product Design Suite Ultimate 2016 requires product key781H1.

I'm using openssl to create an encrypted key in pkcs8 format. Specifically I'm using triple des. An example of the asn1parse output is below. My goal is to take the 'rather long hexadecimal value', which I assume is the encrypted key, and decrypt it using a separate triple des decryption library. The decryption method I would like to use asks for a 24 byte key and an 8 byte input. If you need to convert your key file to a PKCS #8 format, use the following OpenSSL command where is the original non-PKCS #8 formatted key file. (OpenSSL is available on NetSight and NAC appliances. The server.key file can be copied and converted on either appliance.) openssl pkcs8 -topk8 -in key -out server-pkcs8.key –nocrypt.

Certificate chains can be used to securely connect to the Oracle NoSQL Database Proxy. This section provides the steps to generate certificate chains and other required files for a secure connection using OpenSSL.

A certificate chain is provided by a Certificate Authority (CA). There are many CAs. Each CA has a different registration process to generate a certificate chain. Follow the steps provided by your CA for the process to obtain a certificate chain from them.

As a pre-requisite, download and install OpenSSL on the host machine. See OpenSSL .

To generate a certificate chain and private key using the OpenSSL, complete the following steps:

1. On the configuration host, navigate to the directory where the certificate file is required to be placed.
2. Create a 2048 bit server private key.The following output is displayed.
3. This step is required only when your server private key is not in PKCS#8 format. Convert the private key to PKCS#8 format. When prompted, provide a secure password of your choice for the encryption.The following output is displayed.
4. Create a Certificate Signing Request (CSR).where, CN in the subj should map the proxy domain name.
5. Send Certificate Signing Request (CSR) data file to CA. CA will use CSR data to issue a SSL certificate.
6. CA returns a signed certificate certificate.pem. If it is not yet chained up with CA's certificate (rootCA.crt), you need to manually chain up.

• key.pem is the server private key.
• key-pkcs8.pem is the server private key in PKCS#8 format.
• certificate.pem is the certificate chain file in pem format. It includes the server certificate issued by CA and CA intermediate or root certificate.
• request.csr is the server certificate request file.
• rootCA.crt is the root certificate provided by the CA.

While Encrypting a File with a Password from the Command Line using OpenSSLis very useful in its own right, the real power of the OpenSSL library is itsability to support the use of public key cryptograph for encrypting orvalidating data in an unattended manner (where the password is not required toencrypt) is done with public keys.

The Commands to Run

Generate a 2048 bit RSA Key

You can generate a public and private RSA key pair like this:

openssl genrsa -des3 -out private.pem 2048

That generates a 2048-bit RSA key pair, encrypts them with a password you provideand writes them to a file. You need to next extract the public key file. You willuse this, for instance, on your web server to encrypt content so that it canonly be read with the private key.

Export the RSA Public Key to a File

This is a command that is

openssl rsa -in private.pem -outform PEM -pubout -out public.pem

The -pubout flag is really important. Be sure to include it.

Next open the public.pem and ensure that it starts with-----BEGIN PUBLIC KEY-----. This is how you know that this file is thepublic key of the pair and not a private key.

To check the file from the command line you can use the less command, like this:

less public.pem

Do Not Run This, it Exports the Private Key

A previous version of the post gave this example in error.

Public Private Key Encryption

openssl rsa -in private.pem -out private_unencrypted.pem -outform PEM

The error is that the -pubout was dropped from the end of the command.That changes the meaning of the command from that of exporting the public keyto exporting the private key outside of its encrypted wrapper. Inspecting theoutput file, in this case private_unencrypted.pem clearly shows that the keyis a RSA private key as it starts with -----BEGIN RSA PRIVATE KEY-----.

Visually Inspect Your Key Files

It is important to visually inspect you private and public key files to makesure that they are what you expect. OpenSSL will clearly explain the nature ofthe key block with a -----BEGIN RSA PRIVATE KEY----- or -----BEGIN PUBLIC KEY-----.

You can use less to inspect each of your two files in turn:

• less private.pem to verify that it starts with a -----BEGIN RSA PRIVATE KEY-----
• less public.pem to verify that it starts with a -----BEGIN PUBLIC KEY-----

The next section shows a full example of what each key file should look like.

The Generated Key Files

The generated files are base64-encoded encryption keys in plain text format.If you select a password for your private key, its file will be encrypted withyour password. Be sure to remember this password or the key pair becomes useless.

To Use keytool to Create a Server Certificate. Run keytool to generate a new key pair in the default development keystore file, keystore.jks.This example uses the alias server-alias to generate a new public/private key pair and wrap the public key into a self-signed certificate inside keystore.jks.The key pair is generated by using an algorithm of type RSA, with a default password of changeit. RSA keys must be between 2048 and 4096 bits. To generate a new public/private key pair in a Java keystore Use the -genkeypair option to generate a key and save it to a Java keystore. Java server generate key pair. Nov 01, 2018  The API we use to generate the key pairs is in the java.security package. That’s mean we have to import this package into our code. The class for generating the key pairs is KeyPairGenerator. To get an instance of this class we have to call the getInstance methods by providing two parameters. The first parameter is algorithm and the second parameter is the provider. Create a Key Pair You must specify a key pair when you launch an EC2 instance and then specify the private key of the key pair when you connect to the instance. The KeyPairGenerator class is used to generate pairs of public and private keys. Key pair generators are constructed using the getInstance factory methods (static methods that return instances of a given class). A Key pair generator for a particular algorithm creates a public/private key pair that can be used with this algorithm.

The private.pem file looks something like this:

The public key, public.pem, file looks like:

Protecting Your Keys

Depending on the nature of the information you will protect, it’s important tokeep the private key backed up and secret. The public key can be distributedanywhere or embedded in your web application scripts, such as in your PHP,Ruby, or other scripts. Again, backup your keys!

Generate Rsa Key Openssl

Remember, if the key goes away the data encrypted to it is gone. Keeping aprinted copy of the key material in a sealed envelope in a bank safety depositbox is a good way to protect important keys against loss due to fire or harddrive failure.

Oh, and one last thing.

If you, dear reader, were planning any funny business with the private key that I have just published here. Know that they were made especially for this series of blog posts. I do not use them for anything else.
