java.lang.Objectipworkssmime.Snntp
public class Snntp
The SNNTP Bean is used to read and post articles on Usenet news servers.
The SNNTP Bean is the S/MIME enabled equivalent of the
IP*Works! NNTP bean. In addition to standard NNTP functions the SNNTP
bean can sign, encrypt, decrypt, and verify message signatures.
The methods and properties for encrypting, signing, decrypting, and
verifying signatures are identical to those provided with the S/MIME
bean. After setting the certificate properties, and specifying ArticleText
,
call the Encrypt
, Sign
or SignAndEncrypt
method before posting
and the result will be stored in ArticleText
. When attempting to verify
a signed message or when decrypting a message call the Decrypt
, VerifySignature
, or DecryptAndVerifySignature
methods and the resulting
text will be replaced in ArticleText
.
The SNNTP Bean implements a standard Usenet news reader as specified in RFC 977. It can be used to browse Usenet news groups and read and post articles.
The CurrentGroup
property sets the current newsgroup. From then on, news articles from that
group can be read by setting the article number in CurrentArticle
and
then calling the appropriate method. Properties such as ArticleCount
, FirstArticle
, LastArticle
provide information about
the current state.
The headers and text of the articles are received respectively through the Header
and Transfer
events. Additionally, up to MaxLines
from the article body are provided
in the ArticleText
property. The GroupOverview
event returns
information about a range of articles ( OverviewRange
) in CurrentGroup
,
and the GroupList
event is used when listing newsgroup names. The PITrail
event provides a trace of the interaction with the server.
The bean supports posting of articles through the ArticleText
and AttachedFile
properties. The article text is specified in one or both
of the above, and then the PostArticle
method is called.
Article headers are given in a series of properties
like ArticleFrom
, ArticleSubject
, Organization
, etc. that map directly to the
USENET article header with the same name.

public java.lang.String config(java.lang.String configurationString) throws IPWorksSMIMEException
Config
is a generic method available in every bean.
It is used to set and retrieve configuration settings
for the
bean.
Configuration settings are similar in functionality to properties,
but they are rarely used. In order to avoid "polluting" the property
namespace of the bean, access to these internal properties is provided through the Config
method.
To set a configuration setting named PROPERTY , you must call Config("PROPERTY=VALUE") , where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY") . The value will be returned as a string.
The bean accepts one or more of the following configuration settings .
Configuration settings are similar in functionality to properties,
but they are rarely used. In order to avoid "polluting" the property
namespace of the bean, access to these internal properties is provided through the Config
method.

represents the number of headers that are to be saved in the collection
.To save all items to the collection
, set this config to -1. If no
items are wanted, set this to 0, which will not save any to the
collection
. The default for this config is 0, so no items will

FirewallHost
is given, requested connections will be authenticated through the specified firewall
when connecting.If the FirewallHost
setting is set to a Domain Name, a DNS request is initiated. Upon successful termination
of the request, the FirewallHost
setting is set to the corresponding address. If the search is not successful,
an error is returned.
NOTE: This is the same as Host . This setting is provided for use by beans that do not directly expose Firewall properties.
RemoteHost
and RemotePort
are used to tell the SOCKS firewall
in which address and port to listen to. The firewall rules may ignore RemoteHost
, and it is recommended that RemoteHost
be set to empty string in this case.
RemotePort
is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The
binding (address and port) is provided through the ConnectionStatus
event.
The connection to the firewall is made by calling the Connect
method.
FirewallHost
is specified, the FirewallUser
and FirewallPassword
settings
are used to connect and authenticate to the given firewall. If the authentication fails, the bean throws an exception.NOTE: This is the same as Password . This setting is provided for use by beans that do not directly expose Firewall properties.
FirewallPort
is set automatically when FirewallType
is set to a valid value.NOTE: This is the same as Port . This setting is provided for use by beans that do not directly expose Firewall properties.
FirewallPort
is set to 80.
FirewallPort
is set to 1080.
FirewallPort
is set to 1080.
FirewallHost
is specified, the FirewallUser
and FirewallPassword
settings are used to connect and authenticate to the Firewall. If the authentication fails, the bean throws an exception.NOTE: This is the same as User . This setting is provided for use by beans that do not directly expose Firewall properties.
TCPKeepAlive
will automatically be set to true.
By default the operating system will determine the
time a connection is idle before a TCP keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many
cases a shorter interval is more useful. Set this value to the desired interval in milliseconds.Note: This value is not applicable in Java.
TCPKeepAlive
will automatically be set to true.
A TCP keep-alive packet will be sent after a period of inactivity as
defined by KeepAliveTime
. If no acknowledgement is received from the remote host the keep-alive packet
will be re-sent. This setting specifies the interval at which the successive keep-alive packets are sent in milliseconds.
This system default if this value is not specified here is 1 second.Note: This value is not applicable in Java or MAC.
LingerTime
is 0 (default), the
system will attempt to send pending data for a connection until the default
IP protocol timeout expires.
In the second scenario, LingerTime
is a positive value, the system will
attempt to send pending data until the specified LingerTime
is reached.
If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the bean returns control immediately, the system could hold system resources until all pending data is sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.
LocalHost
setting contains the name of the local host
as obtained by the gethostname() system call, or if the
user has assigned an IP address, the value of that address.In multi-homed hosts (machines with more than one IP interface)
setting LocalHost to the value of an interface will make the
bean initiate connections (or accept in the case of server
beans) only through that interface.
If the bean is connected, the LocalHost
setting shows
the IP address of the interface through which the connection
is made in internet dotted format (aaa.bbb.ccc.ddd). In most
cases, this is the address of the local host, except for multi-homed
hosts (machines with more than one IP interface).
LocalPort
after the connection is established.
LocalPort
cannot be changed once a connection is made.
Any attempt to set this when a connection is active will
generate an error.
This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
MaxLineLength
is the size of an internal buffer, which holds received data while waiting for an EOL
string.If an EOL
string is found in the input stream before MaxLineLength
bytes are received, the DataIn
event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL
is found, and MaxLineLength
bytes are accumulated in the buffer, the DataIn
event is
fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength
is 256 bytes. The default value is 2048 bytes. The maximum value is 65536 bytes.
KeepAliveTime
and KeepAliveInterval
to
configure the timing of the keep-alive packets.Note: This value is not applicable in Java.
SSLStatus
event.
Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
When the provider is OpenSSL, SSLCipherStrength is currently not supported.
This functionality is instead made available through the OpenSSLCipherList
config setting.
When the provider is OpenSSL, SSLCipherStrength is currently not supported.
This functionality is instead made available through the OpenSSLCipherList
config setting.
TLS 1.1 and TLS1.2 support are only available starting with Windows 7.
NOTE: setting the property to 0 has the same effect as setting it to 4095 (enables all protocols).
The special value "*" (default) picks the default SSL provider defined in the system. On Windows, this is "Microsoft Unified Security Protocol Provider".
The special value "*" means that the component will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.
Some sample settings:
obj.config("SSLEnabledCipherSuites=*");
obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA");
obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA; SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA");
Possible values include:
SSLEnabledCipherSuites is used together with SSLCipherStrength .
NOTE: This configuration setting is available only for Java products. Possible values are SSL, SSLv2, SSLv3, TLS and TLSv1. Use it only in case your security provider does not support TLS. This is the parameter "protocol" inside the SSLContext.getInstance(protocol) call.

caution as listing groups may take quite a long over slow links. The group names and
other information are returned via the GroupList
event.
If a connection to the NewsServer
doesn't already exist, a new one
is created.
IPWorksSMIMEException
public void listNewGroups() throws IPWorksSMIMEException
This method asks the server to list all the newsgroups created since CheckDate
.
The group names (if any) and other information are returned via the GroupList
event.

public java.lang.String localizeDate(java.lang.String dateTime) throws IPWorksSMIMEException
This method can be used to convert an RFC 822 date/time string to the corresponding local date and time.
Dates will be returned in the format: "MM/dd/yyyy hh:mm:ss".
IPWorksSMIMEException
public void postArticle() throws IPWorksSMIMEException
This method posts the current article and attached file (if any). If a connection to the NewsServer
doesn't already exist, a new one is created.
IPWorksSMIMEException
public void resetHeaders() throws IPWorksSMIMEException
This method resets all the article headers to "" (empty string). Use this method before posting a new article, so that headers from the previous article are not carried over to the next one.
IPWorksSMIMEException
public void setArticleStream(java.io.OutputStream articleStream) throws IPWorksSMIMEException
This method sets the stream to which the article downloaded from the server will be written. If a download stream is set before the FetchArticle
or FetchArticleBody
methods are called, the downloaded data will be written to the stream. The stream should be open and normally set to position 0.
The bean will automatically close this stream if CloseStreamAfterTransfer
is set to true (default). If the stream is closed, you will need to call SetArticleStream
again before calling FetchArticle
or FetchArticleBody
again.
The downloaded content will be written starting at the current position in the stream.
Note: SetArticleStream
and LocalFile
will reset the other.
IPWorksSMIMEException
public void sign() throws IPWorksSMIMEException
Message
.
This method digitally signs the current data included in Message
with the
the certificate provided. Certificates are provided by specifying the Certificate
property. The IncludeCertificate
and DetachedSignature
properties allow you to specify addition details about what to include when
signing the message.
The result of the signed data will be replaced in
the Message
property and the MessageHeaders
property will be filled
with the required S/MIME headers.
IPWorksSMIMEException
public void signAndEncrypt() throws IPWorksSMIMEException
Message
.
This method both signs and encrypts the message data included in Message
into a
single PKCS encoded envelope. The value in DetachedSignature
is
ignored: the bean will always generate an attached signature when
calling this method. All other properties used by calling the Sign
and Encrypt
methods are used in the same manner.
The result of the encrypted data will be replaced in the Message
property and the MessageHeaders
property will be filled with the
required S/MIME headers.
Please note that the message headers, including the Sender, Recipient(s), and Subject, are not encrypted. If this is sensitive information, consider including these headers in the message body as a MIME entity, and providing other headers for the S/MIME wrapper.
IPWorksSMIMEException
public void verifySignature() throws IPWorksSMIMEException
Message
.
This method attempts to verify the signature contained in Message
. If the
message does not have a certificate attached, the bean will attempt
to verify the signature using the certificate supplied in SignerCert
(if any). If no certificate is found, the bean
throws an exception.
If this method is successful, the SignerCert
property will
contain the certificate information of the message signer.
NOTE: This function does not attempt to check the validity of the signing certificate itself.
