MIME Class

Properties   Methods   Events   Config Settings   Errors  

The MIME class allows for the simple encoding and decoding of MIME structures, such as message attachments and file uploads.

Syntax

class ipworksopenpgp.MIME

Remarks

The class may be used for decoding or encoding of messages. message holds the content of the encoded message or the filename that holds the encoded data. The decoded data are provided in parts properties.

To decode a MIME message, you should first assign either the whole message (headers and body) to message or put the message headers into the message_headers property and the message body or the filename holding it into the message property. Calling decode_from_file or decode_from_string directs the class to start parsing the message: it will fill out the content_type and content_type_attr properties with message content-type information, and it will enter information about message parts into the parts properties, which includes part sizes, part content types, part content type attributes, part content disposition, part content disposition attributes, part encoding, part name, part filename, part headers, or part content (part-decoded string or part-decoded file) for each decoded part.

Calling the decode_from_string or decode_from_file to decode does not actually decode the message but only parses it. The real decoding is done when the part content in the parts properties is first accessed.

To encode data into a MIME message, you should first assign values for each part to either a part-decoded string or a part- decoded file in the parts properties property, and optionally assign values to the other part attributes in the parts properties. Assigning a value to the part-decoded string or a part-decoded file through the parts properties, fills out automatically the part headers into the parts properties for the respective part. Calling encode_to_file or encode_to_string directs the class to fill out the message with the message body and the message_headers with the headers.

The on_progress event is fired as the message is parsed and the data are decoded/encoded.

When decoding, call decode_part_to_file to decode a specific part to a file on disk.

The part_idx parameter specifies the index of the item in the array. The size of the array is controlled by the part_count property.

This property is write-only.

part_decoded_string Property

This property holds the actual content of each part.

Syntax

def get_part_decoded_string(part_idx: int) -> bytes: ...
def set_part_decoded_string(part_idx: int, value: bytes) -> None: ...

Default Value

""

Remarks

This property holds the actual content of each part. The class decodes the actual part of message to part_decoded_string when part_decoded_string's value is first queried.

Setting a value to part_decoded_string fills out the corresponding part_size with the string size if the corresponding part_decoded_file is empty.

The class checks during encoding first part_decoded_file: if it is empty, then the class uses the value of part_decoded_string.

Note: It is recommended to use the decode_part method instead of querying this property.

The part_idx parameter specifies the index of the item in the array. The size of the array is controlled by the part_count property.

part_encoding Property

This property contains the actual content encoding type for each part.

Syntax

def get_part_encoding(part_idx: int) -> int: ...
def set_part_encoding(part_idx: int, value: int) -> None: ...

def get_part_file_name(part_idx: int) -> str: ...
def set_part_file_name(part_idx: int, value: str) -> None: ...

Default Value

""

Remarks

This property contains the filename attribute specified in the headers of the part. Changing the value of the corresponding part_decoded_file automatically sets the part_file_name and consequently the part_headers.

The part_idx parameter specifies the index of the item in the array. The size of the array is controlled by the part_count property.

part_headers Property

This property contains the headers for each MIME part.

Syntax

def get_part_headers(part_idx: int) -> str: ...
def set_part_headers(part_idx: int, value: str) -> None: ...

Default Value

""

Remarks

This property contains the headers for each MIME part. The class fills out this property each time any of the other corresponding part properties are changed. If additional headers are needed, they should be appended after all of the other corresponding part properties are set.

""

Remarks

This property contains the name given to a part, such as the filename. Changing the value of part_decoded_file automatically sets the corresponding part_name and consequently the part_headers.

The part_idx parameter specifies the index of the item in the array. The size of the array is controlled by the part_count property.

part_size Property

This property contains the size of the DecodedFile or DecodedString .

Syntax

def get_part_size(part_idx: int) -> int: ...

Default Value

0

Remarks

This property contains the size of the part_decoded_file or part_decoded_string. If a non-empty value is assigned to part_decoded_file, then class fills out the corresponding part_size with the file size; if the file does not exist, an error occurs.

If the part_decoded_file is empty and a value is assigned to part_decoded_string, then the corresponding part_size will be equal to the string's size.

During decoding, this property is filled with the size of that part.

The part_idx parameter specifies the index of the item in the array. The size of the array is controlled by the part_count property.

This property is read-only.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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.

decode_from_file Method

This method decodes from a file.

Syntax

def decode_from_file() -> None: ...

Remarks

This method decodes the data file given in message and optionally message_headers and fills out the parts properties for each decoded part.

Example. Decoding from a File:

MIMEControl.Message = "C:\filename.txt" MIMEControl.DecodeFromFile

In this example, C:\filename.txt must contain the MIME headers and body. If not, the message_headers property must be set to the appropriate MIME headers.

decode_from_string Method

This method decodes from a string.

Syntax

def decode_from_string() -> None: ...

Remarks

This method decodes from a string. It is the same as DecodeFromFile, but now the message denotes the real encoded message rather than a filename.

This method decodes the data given in message and optionally message_headers and fills out the parts properties.

Example. Decoding a Mail Message:

MIMEControl.MessageHeadersString = MailControl.MessageHeaders MIMEControl.Message = MailControl.MessageText MIMEControl.DecodeFromString

decode_part Method

This method decodes the specified part.

Syntax

def decode_part(index: int) -> bytes: ...

Remarks

This method decodes the part specified by Index and returns the decoded part data.

decode_from_string or decode_from_file must be called before calling this method. Calling this method will return the decoded bytes, and in addition, the part_decoded_string property will be populated with the string representation of the decoded data.

Example. Decoding a Specified Part: mime.MessageHeadersString = myMessageHeaders; mime.Message = myMessageBody; mime.DecodeFromString(); byte[] myPartContent = await mime.DecodePart(0);

decode_part_to_file Method

This method decodes the specified part to a file on disk.

Syntax

def decode_part_to_file(index: int) -> str: ...

Remarks

This method decodes the part specified by Index to a temporary file. The full path to the temporary file is returned by this method. The user is responsible for deleting the temporary file.

decode_from_string or decode_from_file must be called before calling this method.

encode_to_file Method

This method encodes to a file.

Syntax

def encode_to_file() -> None: ...

Remarks

This method encodes the data given in parts properties (either a decoded file or a decoded string) into a MIME message at message and message_headers using the values optionally given in parts properties. To encode several objects into a MIME envelope, the user should first clear any old values left in the parts properties.

The class will check for each item in parts properties (first the decoded file and then the decoded string) for the data to encode.

The encoded message will be saved in the file pointed to by message; the message headers will be held by message_headers.

Example. Encoding Data:

MIMEControl.ResetData() MIMEControl.PartCount = 2 MIMEControl.PartDecodedString(0) = "This is plain text data" MIMEControl.PartEncoding(0) = peQuotedPrintable MIMEControl.PartContentType(0) = "text/plain" MIMEControl.PartDecodedFile(1) = "C:\filename.txt" MIMEControl.Message = "temp.tmp" MIMEControl.EncodeToFile()

encode_to_string Method

This method encodes to a string.

Syntax

def encode_to_string() -> None: ...

Remarks

This method encodes to a string. It is the same as encode_to_file but the encoded data are held in the message property rather than saved to a file.

This method encodes the data given in the parts properties into a MIME message. The message gets stored in message and message_headers using the values optionally given in parts properties. To encode several objects into a MIME envelope, the user should first clear any old values left in the parts properties by calling reset_data.

The class will check each item in the parts properties (first the decoded file and then the decoded string) for the data to encode.

The encoded message will be stored in the message property; the message headers will be held by message_headers.

Example. Encoding Data:

MIMEControl.ResetData() MIMEControl.PartCount = 2 MIMEControl.PartDecodedString(0) = "This is plain text data" MIMEControl.PartEncoding(0) = peQuotedPrintable MIMEControl.PartContentType(0) = "text/plain" MIMEControl.PartDecodedFile(1) = "C:\filename.txt" MIMEControl.EncodeToString()

reset Method

This method will reset the class.

Syntax

def reset() -> None: ...

Remarks

This method will reset the class's properties to their default values.

reset_data Method

This method resets the values of all headers and part properties.

Syntax

def reset_data() -> None: ...

Remarks

This method resets the values of all headers and part properties. It is an easy way to reset the class's properties before starting to populate the part properties with new values.

on_error Event

Fired when information is available about errors during data delivery.

Syntax

class MIMEErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class MIME:
@property
def on_error() -> Callable[[MIMEErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[MIMEErrorEventParams], None]) -> None: ...

Remarks

The on_error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

on_header Event

This event is fired every time a header is parsed.

Syntax

class MIMEHeaderEventParams(object):
  @property
  def part_index() -> int: ...

  @property
  def field() -> str: ...

  @property
  def value() -> bytes: ...

# In class MIME:
@property
def on_header() -> Callable[[MIMEHeaderEventParams], None]: ...
@on_header.setter
def on_header(event_hook: Callable[[MIMEHeaderEventParams], None]) -> None: ...

Remarks

The PartIndex parameter contains the index of the part containing the current header. If the header is from the MIME body, this value will be -1. The Field parameter contains the name of the MIME header. The Value parameter contains the header contents. The on_header event is fired when a header is parsed, which occurs for each header of the message when decode_from_file, decode_from_string, or decode_from_stream is called.

on_progress Event

This event shows the progress of decoding or encoding the input data.

Syntax

class MIMEProgressEventParams(object):
  @property
  def percent_done() -> int: ...

# In class MIME:
@property
def on_progress() -> Callable[[MIMEProgressEventParams], None]: ...
@on_progress.setter
def on_progress(event_hook: Callable[[MIMEProgressEventParams], None]) -> None: ...

Remarks

The on_progress allows the user to visualize the progress of processing the input data.

The PercentDone parameter shows what percentage of the input has been read.

MIME Config Settings

The class 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 class, access to these internal properties is provided through the config method.

MIME Config Settings

DecodeMessageHeaders:   Instructs the component to automatically decode message headers.

Message headers that have been Quoted-Printable or Base64 encoded are automatically decoded when this configuration setting is True. The default value of this setting is False.

IncludeHeaders:   Tells the class whether to include the headers when encoding the message.

If True, the class will include the headers when encode_to_file or encode_to_string are called. If False, only the message will be encoded.

The default value for IncludeHeaders is False.

RequireVersionHeader:   Specifies whether or not the class should require the version header.

If True, the class will require that the "MIME-Version" header be included in the message_headers. If the header is not present during decoding, the component fails with an error. This configuration setting is False by default.

SanitizeFileName:   Whether invalid characters are replaced in MIME part filenames.

If True, the class will replace invalid characters with an underscore when decoding the MIME message. This applies to the filename held in the part_file_name property. When True, the following characters are considered invalid:

  • \
  • /
  • "
  • :
  • ?
  • *
  • <
  • >
  • |
Any characters with ASCII values between 0 and 31 are also considered invalid. The default value is False.
TempFilePath:   If set, the temporary files created during MIME decoding and encoding will be put in the path specified.

The TempFilePath property sets the path at which the temporary files will be created.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitiveData:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to True to mask sensitive data. The default is True.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when do_events is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseFIPSCompliantAPI:   Tells the class whether or not to use FIPS certified APIs.

When set to True, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to True. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details, please see the FIPS 140-2 Compliance article.

Note: This setting is applicable only on Windows.

Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to False, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to True tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to False by default. On Linux/macOS, this setting is set to True by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
