Implements a generic client or server SSL context.

TIdSSLContext = class(TObject)

TIdSSLContext is a class that provides an implementation of a Secure Socket Layer Context. TIdSSLContext is used by TIdSSLConnectionIntercept descendants and TIdSSLSocket to allow a client or server SSL socket to connect using the desired SSL options and certificates.

File containing the X.509 certificate.

property CertFile: String;

CertFile is a String property that represents the file name that contains the content for the X.509 certificate.

File containing the Key for the X.509 certificate.

property KeyFile: String;

KeyFile is a String property that represents the file name containing the contents for the X.509 certificate Key.

SSL version and method for the X.509 certificate.

property Method: TIdSSLVersion;

Method is a TIdSSLVersion property that identifies the SSL version number required, and the authentication method used for the X.509 certificate.

Authentication mode for the X.509 certificate.

property Mode: TIdSSLMode;

Mode is a TIdSSLMode property that identifies the authentication mode for the X.509 certificate.

File for the Root certificate for the X.509 certificate.

property RootCertFile: String;

RootCertFile is a String property that identifies the file containing the content for the Root Certification Authority for the X.509 certificate.

Indicates that the context can use status events.

property StatusInfoOn: Boolean;

StatusInfoOn is a Boolean property that indicates when the SSL context can use the OnStatusInfo event handler for context status notifications.

Maximum number of links for the X.509 certificate.

property VerifyDepth: Integer;

VerifyDepth is an Integer property that represents the maximum number of links permitted when verification is performed for the X.509 certificate.

Verification options for the SSL content.

property VerifyMode: TIdSSLVerifyModeSet;

VerifyMode is a TIdSSLVerifyModeSet property that represents the Verification options permitted for the SSL contents using the X.509 certificate

Indicates that the context can use authentication events.

property VerifyOn: Boolean;

VerifyOn is a Boolean property that indicates when the SSL context can use the OnVerifyPeer event handler for context authentication actions.

Constructor for the object instance.

constructor Create;

Create is the constructor for the object instance. On the Windows platform, Create will attempt to load the OpenSSL support .DLLs. If an error occurs while loading the support .DLLs, an EIdOSSLCouldNotLoadSSLLibrary exception will be raised.

Create sets Mode to sslmUnassigned.

Frees the object instance.

destructor Destroy; override;

Destroy is the destructor for the object instance. Destroy frees the SSL context, and calls the inherited Destroy method.

Loads the certificate file for the SSL context.

function LoadCert: Boolean;

Boolean - True on success.

LoadCert is a Boolean function that loads the certificate file in CertFile for the SSL context. LoadCert returns True if the certificate file is loaded, or False when the file does not exist or does not contain a valid PEM X.509 certificate.

Loads the key file for the SSL context.

function LoadKey: Boolean;

Boolean - True on success.

LoadKey is a Boolean function that loads the X.509 certificate key file for the SSL context. LoadKey returns True if the Key file is loaded for the SSL context, and False if an error occurs while loading the key file or the file does not contain a valid X.509 PEM certificate key.

Loads the root certificate file for the SSL context.

function LoadRootCert: Boolean;

Boolean - True on success.

LoadRootCert is a Boolean function that loads the root certificate file in RootCertFile for the SSL context. LoadRootCert returns True if the root certificate file is loaded, or False when the file does not exist or does not contain a valid PEM X.509 certificate.
