S/MIME Message Description

The SMimeMessage ActiveX control implements the S/MIME standard for encryption and decryption with public key cryptography and X.509 digital certificates. In addition, the component can be used for both generating and verifying RSA digital signatures. This component implements an S/MIME mail message as described in the Internet Standards documents: RFC 2311, RFC 2633 and RFC 2045

This component allows you to compose / parse messages in an alternative MIME format with multiple file attachments and digitally sign / verify, encrypt / decrypt them according to the S/MIME standard.

The SMimeMessage control is an independent stand-alone component and does not have ties with the Clever Internet ActiveX Suite mail socket engine. It is possible to use this component with any other mail client engines / components for composing and signing mail messages formatted according to the RFC standards.

Please see the Demos code (SMime) and also the indexed Help documentation provided with the Clever Internet Suite installation for more details about using this component.

The most common members of the SMimeMessage control can be seen below:

Supported Message Bodies

Name   Description  IclEnvelopedBody Is the class that implements the encrypted / signed data storage for the S/MIME mail components (difital signatures, signed blobs ...).  IclSMimeBody Is the class that implements the signed message storage for the S/MIME mail components.  IclTextBody Implements the text / html message bodies storage for the mail components.  IclAttachmentBody Implements the file attachment storage for the mail components.  IclImageBody Implements the image storage for the mail components.  IclMultipartBody Implements the MIME multipart storage for the mail components.

Property List

Name   Description  BCCList Specifies blind carbon copy recipients for the message.  Bodies Represents a body collection of the message.  BodiesSource Gets a string list with the message bodies' parts.  Boundary Represents a character sequence that delimits the message bodies.  CCList Specifies carbon copy recipients for the message.  Certificates Gets the TclMessageCertificates collection of the TclCertificate objects.  CharSet Represents the character set used for the message.  ContentType Represents the MIME body type for the message.  Date Represents the date when message was sent.  Encoding Represents the encoding method for the message.  From Identifies the original author of the message.  Header Represents the necessary information about message header fields.  HeaderSource Gets or sets the the given string list with the message header part.  IsDetachedSignature Specifies whether to include a detached signature when signing a message.  IsEncrypted Determines whether the current message content is encrypted.  IsIncludeCertificate Specifies whether the signer's certificate with the signed message should be included.  IsSigned Determines whether the current message content is signed.  MessageFormat Contains the format of parsed message.  MessageID Specifies the message identifier assigned to the message.  MessageSource Gets or sets the the given string list with the mail message source.  NewsGroups Identifies newsgroup to receive the message.  Priority Specifies the message priority for the mail server.  ReadReceiptTo Specifies the the email address to which the recipient of the original message should reply with notification about receiving the message.  References Is used by NNTP newsreader applications to create a threaded article display.  ReplyTo Identifies the delivery address for message replies.  Subject Specifies the subject for the message.  ToList Provides mail message recipients.

Method List

Name   Description  BuildMessage, BuildMessageWithAttachments, BuildMessageWithHtml Allows to build mail message using text and html message representations including both images and files attachment lists.  Clear Cleans all message members and assigns them to their initial values.  Decrypt Decodes and decrypts the current mail message.  DecryptAndVerify Decrypts and verifies the signature of the current mail message.  Encrypt Encodes and encrypts the current mail message?  GetBodyText Gets a text representation of the mail message content.  Sign Signs the current mail message.  Verify Verifies the signature of the current mail message.

Event List

Name   Description  OnChanged Occurs when a property value has been changed.  OnEncodingProgress Occurs when the encoding / decoding is in process.  OnGetFileNameForBody Occurs when the message parser is about to store the body of the message being parsed into the file.  OnGetCertificate Occurs when the S/MIME parser is about to Encrypt, Sign, Decrypt or Verify the current mail message.
