Certificates</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>The Symbian certstore allows two types of certificates to be imported:

root certificates and user certificates. </p>

<p>Please note that certificates must be in DER format to be imported. Also,

the absolute path to the certificate file must be given regardless of the

current directory in the shell. For example, if you are in the directory c:\temp

which contains mycert.der, to import the certificate you must issue the command: </p>

<p><userinput>certtool –import c:\temp\mycert.der</userinput> </p>

<p>A certificate always has a label associated with it. A label can be specified

during the import operation with the –label option, if this option is not

present, the full path to the certificate file is taken as label. Labels must

be unique within a specific certstore implementation. If a label is not unique,

an error occurs. For instance, if the certstore contains a certificate with

label abc: </p>

<p><userinput>certtool –list abc</userinput> </p>

<p>However, this happens because of the attempt made to insert the certificate

in a certstore implementation where the same label already exists. Certstore

implementation is not specified for use in a command. It is possible to insert

the certificate with label abc in the certstore implementation with index

1 (Index 0 is used by default). </p>

<p><b>Importing root certificates </b> </p>

<p>Root certificates typically belong to a certificate authority (CA) and

a number of them are present on a final product. Root certificates are used

to verify the authenticity of signed content. Root certificates are self-signed,

and often termed top-level certificates. </p>

<p>All the examples in the previous sections referred to root certificates. </p>

<p>A certificate is imported as a CA root certificate if and only if the corresponding

private key cannot be found in the keystore. </p>

<p><b>Importing user certificates </b> </p>

<p>User certificates belong to the phone owner. Using user certificate, the

phone owners can authenticate themselves. For example, during SSL/TLS, the

owner can perform client authentication. To import a user certificate both

the certificate and its corresponding private key must be stored in the Symbian

keystore. </p>

<p>If the private key corresponding to a given certificate is already present

in the Symbian keystore, the certificate will be automatically imported as

a user certificate. </p>

<p>Assume that the private DSA key corresponding to the certificate stored

in dsa_cert1.der is present in the Symbian keystore. The following command

imports the certificate as a user certificate: </p>

<p><userinput>certtool –label abc –import c:\certstore\data\dsa_cert1.der</userinput> </p>

<p>If the private key is not already present in the keystore, the same command

imports the certificate as a CA certificate. </p>

<p>Keytool can be used to include private keys in the Symbian keystore. Alternatively,

if you only want to include a user certificate, point to a DER-encoded PKCS8

file containing the key using the <codeph>-private</codeph> option. After

importing the key, <codeph>certtool</codeph> will make the owner of the key

as "WriteDeviceData", so that keytool will able to manipulate the key, performing

actions such as <codeph>remove</codeph> or <codeph>setuser</codeph>. </p>

<p>Assume the DSA private key corresponding to the certificate stored in <filepath>dsa_cert1.der</filepath> is

not present in the keystore and that the required DSA private key is stored

in pkcs8 DER-encoded format in the file <filepath>pkcs8dsa1.001</filepath>. </p>

<p><userinput>certtool –label abc –private c:\certstore\data\pkcs8dsa1.001

–import c:\certstore\data\dsa_cert1.der </userinput> </p>
