getUsername

public String getUsername()

Get the username that is required to authenticate with the file server.

Returns:

A username or null if authentication is not required

public void setUsername(String username)
                 throws PermissionDeniedException,
                        InvalidDataException

getServerCertificate

public byte[] getServerCertificate()

Get the public server certificate that indicates that we should only trust the server if it can present a certificate that matches this. This property is typically only needed to access servers using https that has a self-signed certificate. Servers which has a valid certificate signed by a trusted certification authority should be automatically trusted by BASE without setting this property. The certificate must be a X.509 certificate in either binary or base64-encoded DER format.

Returns:

A byte array with the certificate or null if no certificate has been set

See Also:

getServerX509Certificate()

setServerCertificate

public void setServerCertificate(byte[] certificate)

Set the public server certificate so that BASE can trust https connections to the server. See getServerCertificate() for more information. The certificate must be a X.509 certificate in either binary or base64-encoded DER format.

Parameters:

certificate - The server certificate or null if no certificate is required

getServerX509Certificate

public X509Certificate getServerX509Certificate()

Get the X.509 certificate for the server.

Returns:

The server certificate or null if no certificate has been specified

getClientCertificate

public byte[] getClientCertificate()

Get the client certificate that BASE should use to authenticate with the server when connecting with https. This property is typically needed when the server requires clients to authenticate themselves using a certificate. The certificate must be a PKCS #12 certificate in binary format, and it should contain only one certificate. NOTE! WRITE permission is required to read this property since it may contain sensitive data, use getClientX509Certificate() to get the public information from the certificate.

Returns:

A byte array with the certificate or null if no certificate has been set

See Also:

getClientX509Certificate()

setClientCertificate

public void setClientCertificate(byte[] certificate)

Set the client certificate that BASE should use to authenticate with the server when connecting with https. The certificate must be a PKCS #12 certificate in binary format, and it should contain only one certificate.

Parameters:

certificate - The client certificate or null if no certificate is required

getClientX509Certificate

public X509Certificate getClientX509Certificate()

Get the X.509 certificate for the client.

Returns:

The client certificate or null if no certificate has been specified

getClientCertificatePassword

public String getClientCertificatePassword()

Get the password that is needed to unlock the client certificate. NOTE! WRITE permission is required to read this property.

Returns:

The password (which may be null)

setClientCertificatePassword

public void setClientCertificatePassword(String password)
                                  throws PermissionDeniedException,
                                         InvalidDataException

getSSLSocketFactory

public org.apache.http.conn.ssl.SSLSocketFactory getSSLSocketFactory()

Get a socket factory that can be used to create SSL connections to the given server. If a server and/or client certificate has been specified for this file server the socket factory will be created with those certificates. Otherwise, the default (as configured in base.config) certificates are used.
