May 23, 2016 Once the keys are generated, click on Save Private Key, Save Public Key and copy paste the key to be pasted in authorizedkeys file and save. Now, you will have 3 files generated. PPK private key, SSH public Key, SSH Public key to be pasted on to SFTP server. Public Keys, Private Keys, and Certificates. When performing authentication, SSL uses a technique called public-key cryptography. Public-key cryptography is based on the concept of a key pair, which consists of a public key and a private key.Data that has been encrypted with a public key can be decrypted only with the corresponding private key. To use SSL, the AS Java must possess a key pair which consists of a public key (distributed using a X.509 public-key certificate) and a corresponding private key. To use a key pair for SSL, the public key of the AS Java key pair must be certified by a well known Certification Authority (CA) that clients using SSL trust. Can I generate a new private key for my SSL certificate? Since a public key with the additional information (i.e., domain name and administrative contact information) must be signed by a trusted certificate authority in order to make it applicable and legitimate for securing communication with your server, it wouldn’t make much sense if we.
Jan 06, 2013 In order to support signing and encryption in integration scenarios with SAP Process Orchestration (PO) and/or SAP Process Integration (PI) it is often necessary to load and access public/private keys and certificates from the Key Storage. This blog describes the steps required in order to use that functionality from the Key Storage of SAP. 4.4 Generate Certificate Request for Signing. Select the certificate created in the previous step and click in Generate CSR Request. Use the Base64 format and click Download. Send the downloaded file to the Certificate Authority to be signed. The following steps illustrate an example of how to sign a certificate request with the SAP.
Configuring the SSL Key Pair and Trusted X.509 Certificates
Use
You can use the procedure below to configure the key pair and trusted client certificates to use for establishing SSL connections on the AS Java. You create a new key pair or upload an existing key pair or a trusted X.509 client certificate from the file system.
For SSL, the server needs a key pair that is associated with its fully-qualified host name that is used to access the server. If multiple hosts are accessed using the same fully-qualified host name, then you only have to create one key pair and use it for all hosts.
To use SSL, the AS Java must possess a key pair which consists of a public key (distributed using a X.509 public-key certificate) and a corresponding private key. To use a key pair for SSL, the public key of the AS Java key pair must be certified by a well known Certification Authority (CA) that clients using SSL trust. Therefore, you create a certificate signing request (CSR) that you then send to the CA of your choice. After receiving the CSR, the CA returns the corresponding signed public-key certificate in the form of a certificate request response, which you then import into the key pair for which you created the request.
Prerequisites
●To import an existing key pair or a trusted X.509 client certificate, the key pair must exist in the file system in a specific format. For more information about the supported formats, see How to Use Key Storage.
●The certificate request response that you receive from the CA must exist as a DER (Distinguished Encoding Rules) or as a Base 64-encoded file.
Procedure
..
1.Using the Key Storage management functions of the SAP NetWeaver Administrator (NWA), open the Content tab. For more information about managing keys and certificates in the Key Storage, see Managing Entries.
2.From the list of Keystore Views, select the ICM_SSL_<instance_ID> keystore view. The contents of the selected keystore view appear.
By default, the keystore view contains a key pair that is created during installation for using SSL on the AS Java. This key pair is signed by a testing CA, therefore we recommend that you limit the use of the default certificate to testing purposes.

The AS Java uses the ICM_SSL_<instance_ID> keystore view to store the key pair and trusted client certificates to use for SSL. In addition, the keystore view service_ssl contains backup copies of the default key pair and trusted certificates to use for SSL. These keystore views can contain a single key pair entry and an arbitrary number of trusted X.509 client certificate entries to use for establishing AS Java connections secured with SSL.
Proceed as shown in the table below to configure the key pair and trusted client certificates to use for SSL connections:
Task | Procedure |
Import a saved key pair entry | .. a.Choose Remove Entry for the existing AS Java key pair entry in the ICM_SSL_<instance_ID> view.Windows xp sp3 license key generator. b.Choose Import Entry. The Entry Import dialog appears. c.Choose the PKCS type for the key pair to import and enter the path and password for the PKCS file. d.Choose Import to add the key pair entry to the keystore view. |
Import trusted X.509 client certificates for SSL | .. To use SSL with client certificates, you also have to configure the VCLIENT parameter for the instance profile of the AS Java ICM. For more information, see Maintaining ICM Parameters for SSL. a.Choose Import Entry. The Entry Import dialog appears. b.Choose X.509 Client Certificate for the entry type to import and enter the path to stored X.509 certificate. c.Choose Importto add the trusted X.509 certificate to the ICM_SSL_<instance_ID> keystore view. |
Create new key pair entry to use for SSL | .. a.Choose Remove Entryfor the existing AS Java key pair entry in the ICM_SSL_<instance_ID> view. b.Choose Add Entry to create a new key pair. c.Follow the Add New Keystore Entry wizard that appears. Note the following: ■Specify the name to use to identify the private key entry in the keystore view in step 1 of the wizard. ■In step 1 of the wizard, select the Store certificate option to save the server’s public-key certificate separately so that you can export it at a later time. ■Select RSA as the Algorithm to use. ■Specify the server’s fully-qualified host name as the Common Name part of the Distinguished Name in step 2 of the wizard dialog. Otherwise, certain Web browsers can produce a warning if the host name that users use to access the server does not match the host name found in the server’s public-key certificate. |
Generate a certificate signing request: | You need to perform this configuration step if the corresponding certificate has not yet been signed by a CA. We recommend that you use a well known CA that your client systems trust for signing the SSL keys. .. a.Select the SSL key entry. b.Choose Generate CSR Request. c.Save the CSR request to a file. d.Send the certificate signing request to a CA to be signed. The exact procedure to use depends on the CA that you use. For the SAP CA, follow the instructions provided by the SAPTrustCenter Service at service.sap.com/tcs. e.Save the certificate request response to a file in the file system. Use the extension .crt (DER-encoded or Base-64 encoded) or .cert (Base-64 encoded). f.To import the corresponding certificate request response, choose Import CSR Response and load the response from the file system. |
3.Restart the SSL service of the AS Java to make the SSL key pair change effective.

The server possesses a public and private key pair to use for SSL. To verify that the import was successful, select the private key entry. The certificate should contain the name of the CA as the issuer.
