Generating Server Certificate and Server Private Key

Sso Generate Private Key Net Core 2 0

The following procedures generate the server certificate and server private key that BI components acting as servers must possess. The server certificate and private key is used by Oracle BI Cluster Controller, Oracle BI Server, Oracle BI Scheduler, Oracle BI Presentation Services and Oracle BI Presentation Services Plug-in (ISAPI) components.

Sep 18, 2017  JWT Token Authentication with Cookies in ASP.NET Core. Client requests exchange a client id and secret key for an access token that they then pass in each request to the server to establish identity and claims. ASP.NET Core’s default cookie authentication also uses it to generate a secure authentication ticket and packs in the claims. Sep 12, 2014 The -nodes option specifies that the private key should not be encrypted with a pass phrase. The -new option, which is not included here but implied, indicates that a CSR is being generated. Generate a CSR from an Existing Private Key. Use this method if you already have a private key that you would like to use to request a certificate from a CA. I have calculated n, e, d, p, q values of an RSA key. Now, how can I generate a private key file (pem or der) with openssl command line tools? I was thinking about. Openssl asn1parse -genconf asn1.cnf -noout -out asn1.der but I cannot understand how to build the conf file. It is more secure because it uses public/private key in the form of an X.509 certificate for signing. In this post, I will explain how to create application using Angular 6 app with ASP.net core 2.1 and do the token-based authentication using JWT. The following software needs to be installed in our system before starting the work. By Rick Anderson. ASP.NET Core Identity is a membership system that adds login functionality to ASP.NET Core apps. Users can create an account with the login information stored in Identity or they can use an external login provider.

Generating Server Certificate Request and Private key

Use the following procedure to generate the server certificate request and private key.

To generate the server certificate request and private key

  • Run the following command:

    req -new -keyout $ServerKeyFilename -out $ServerRequestFilename -days $ValidityPeriod -config openssl.cnf

    For example:

    OpenSSL> req -new -keyout server-key.pem -out server-req.pem -days 365 -config openssl.cnf

    This example generates the following dialog:

    Loading 'screen' into random state - done
    Generating a 1024 bit RSA private key
    ..............++++++
    ..............................++++++
    writing new private key to 'server-key.pem'
    Enter PEM pass phrase:
    Verifying - Enter PEM pass phrase:
    -----

    You are about to be asked to enter information that will be incorporated into your certificate request.
    What you are about to enter is what is called a Distinguished Name or a DN.
    There are quite a few fields but you can leave some blank
    For some fields there will be a default value,
    If you enter '.', the field will be left blank.
    -----
    Country Name (2 letter code) [AU]:US
    State or Province Name (full name) [Some-State]:
    Locality Name (eg, city) []:
    Organization Name (eg, company) [Some-Organization Pty Ltd]:
    Organizational Unit Name (eg, section) []:
    Common Name (eg, YOUR name) []:
    Email Address []:

    Please enter the following 'extra' attributes
    to be sent with your certificate request
    A challenge password []:
    An optional company name []:

  • Enter a Distinguished Name as prompted. The Distinguished Name identifies the server.
  • Make a note of the passphrase that you entered. This passphrase is needed to decrypt the private key.
  • Use the IIS Manager to configure the web.config file of an ASP.NET Core app that has already been deployed to the server. If you haven't already done so, enable IIS to host ASP.NET Core apps. For more information, see Host ASP.NET Core on Windows with IIS.
  • Mar 23, 2018  Everything you ever wanted to know about token authentication in ASP.NET Core 2.0 and beyond. Instead, a public/private keypair is used: the authorization server signs tokens with a secret private key, and publishes a public key that anyone can use to validate tokens. To roll your own full-fledged OpenID Connect authorization server.

The command generates the server private key file called server-key.pem and the certificate request (unsigned server certificate) called server-req.pem.

Creating the Server Certificate

The certificate request created above can be submitted to a commercial CA to generate a server certificate. For testing purposes, the CA generated in the step Creating the Certificate Authority (CA) Certificate can be used to sign the request, as described in the following procedure.

To create the server certificate

  • Run the following command:

    ca -policy policy_anything -out $ServerCertFilename -config openssl.cnf -infiles $ServerRequestFilename

    For example:

    Openssl>ca -policy policy_anything -out server-cert.pem -config openssl.cnf -infiles server-req.pem

    For this example, the following dialog is received:

    Using configuration from openssl.cnf
    Loading 'screen' into random state - done
    Enter pass phrase for ./private/cakey.pem:
    Check that the request matches the signature
    Signature ok
    The Subject's Distinguished Name is as follows
    countryName :PRINTABLE:'US'
    stateOrProvinceName :PRINTABLE:'CA'
    localityName :PRINTABLE:'Redwood Shores'
    organizationName :PRINTABLE:'Oracle'
    organizationalUnitName:PRINTABLE:'BI'
    commonName :PRINTABLE:'Server Certificate'
    Certificate is to be certified until Dec 29 07:06:45 2007 GMT (365 days)
    Sign the certificate? [y/n]:y

    1 out of 1 certificate requests certified, commit? [y/n]y
    Write out database with 1 new entries
    Data Base Updated

  • When prompted, enter the passphrase for the private key of the CA.

    This is the passphrase that was supplied when creating the private key cakey.pem in the topic Creating the Certificate Authority (CA) Certificate.

This command generates the server certificate named server-cert.pem. The private key of the CA was used to sign the request. The public key is generated and placed in $DIRnewcerts with a filename that reflects the serial number, for example, 01.pem.

The server certificate and private key is used by Oracle BI Cluster Controller, Oracle BI Server, Oracle BI Scheduler, Oracle BI Presentation Services and Oracle BI Presentation Services Plug-in (ISAPI) components.

Creating and managing keys is an important part of the cryptographic process. Symmetric algorithms require the creation of a key and an initialization vector (IV). The key must be kept secret from anyone who should not decrypt your data. The IV does not have to be secret, but should be changed for each session. Asymmetric algorithms require the creation of a public key and a private key. The public key can be made public to anyone, while the private key must known only by the party who will decrypt the data encrypted with the public key. This section describes how to generate and manage keys for both symmetric and asymmetric algorithms.

Symmetric Keys

The symmetric encryption classes supplied by the .NET Framework require a key and a new initialization vector (IV) to encrypt and decrypt data. Whenever you create a new instance of one of the managed symmetric cryptographic classes using the parameterless constructor, a new key and IV are automatically created. Anyone that you allow to decrypt your data must possess the same key and IV and use the same algorithm. Generally, a new key and IV should be created for every session, and neither the key nor IV should be stored for use in a later session.

Public Private Key Encryption

To communicate a symmetric key and IV to a remote party, you would usually encrypt the symmetric key by using asymmetric encryption. Sending the key across an insecure network without encrypting it is unsafe, because anyone who intercepts the key and IV can then decrypt your data. For more information about exchanging data by using encryption, see Creating a Cryptographic Scheme.

The following example shows the creation of a new instance of the TripleDESCryptoServiceProvider class that implements the TripleDES algorithm.

When the previous code is executed, a new key and IV are generated and placed in the Key and IV properties, respectively.

Sometimes you might need to generate multiple keys. In this situation, you can create a new instance of a class that implements a symmetric algorithm and then create a new key and IV by calling the GenerateKey and GenerateIV methods. The following code example illustrates how to create new keys and IVs after a new instance of the symmetric cryptographic class has been made.

When the previous code is executed, a key and IV are generated when the new instance of TripleDESCryptoServiceProvider is made. Another key and IV are created when the GenerateKey and GenerateIV/avast-driver-updater-serial-key-generator.html. methods are called.

Asymmetric Keys

The .NET Framework provides the RSACryptoServiceProvider and DSACryptoServiceProvider classes for asymmetric encryption. These classes create a public/private key pair when you use the parameterless constructor to create a new instance. Asymmetric keys can be either stored for use in multiple sessions or generated for one session only. While the public key can be made generally available, the private key should be closely guarded.

A public/private key pair is generated whenever a new instance of an asymmetric algorithm class is created. After a new instance of the class is created, the key information can be extracted using one of two methods:

  • The ToXmlString method, which returns an XML representation of the key information.

  • The ExportParameters method, which returns an RSAParameters structure that holds the key information.

Both methods accept a Boolean value that indicates whether to return only the public key information or to return both the public-key and the private-key information. An RSACryptoServiceProvider class can be initialized to the value of an RSAParameters structure by using the ImportParameters method. Adobe dreamweaver cs6 cd-key generator.

Asymmetric private keys should never be stored verbatim or in plain text on the local computer. If you need to store a private key, you should use a key container. For more on how to store a private key in a key container, see How to: Store Asymmetric Keys in a Key Container.

The following code example creates a new instance of the RSACryptoServiceProvider class, creating a public/private key pair, and saves the public key information to an RSAParameters structure.
