Detailed Description

This class implements the output stream to encode ASN.1 messages as specified in the Canonical Encoding Rules (CER) as specified in the ITU-T X.690 standard. A reference to an object of this type is passed to each of the ASN.1 type encode methods involved in encoding a particular message type.

Constructor & Destructor Documentation

◆ Asn1CerOutputStream() [1/2]

Asn1CerOutputStream ( System.IO.Stream os )

This constructor creates a buffered CER output stream object with default size of buffer. Whenever the buffer becomes full, the buffer will be flushed to the stream.

Parameters

os	The underlying System.IO.Stream object.

◆ Asn1CerOutputStream() [2/2]

Asn1CerOutputStream	(	System.IO.Stream	os,
		int	bufSize
	)

This constructor creates a buffered CER output stream object. Whenever the buffer becomes full, the buffer will be flushed to the stream.

Parameters

os	The underlying System.IO.Stream object.
bufSize	The buffer size. If it is 0 then the output stream is used as unbuffered one.

Member Function Documentation

◆ Encode()

override void Encode	(	Asn1Type	type,
		bool	explicitTagging
	)

virtual

This method encodes and writes to the stream ASN.1 types. The UNIVERSAL tag value and length is also encoded if explicit tagging is specified (the universal identifier must be provided by the caller).

Throws, exception thrown by the underlying System.IO.Stream object.

Parameters

type	The object to be written
explicitTagging	Flag indicating explicit tagging should be done

Reimplemented from Asn1BerOutputStream.

References Asn1Type.Encode().

◆ EncodeBitString()

override void EncodeBitString	(	byte []	value,
		int	numbits,
		bool	explicitTagging,
		Asn1Tag	tag
	)

virtual

This method writes the given array of bytes as bit string value.

Throws, exception thrown by the underlying System.IO.Stream object.

Parameters

value	Byte array containing data to encode.
numbits	Number of bits to encode
explicitTagging	Flag indicating explicit tagging should be done
tag	Universal tag to apply

Exceptions

Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1BerOutputStream.

References Asn1BitString._TAG, Asn1Tag.CONS, Asn1Tag.mClass, and Asn1Tag.mIDCode.

◆ EncodeBMPString()

override void EncodeBMPString	(	System.String	value,
		bool	explicitTagging,
		Asn1Tag	tag
	)

virtual

This method writes the given string as BMP string value.

Throws, exception thrown by the underlying System.IO.Stream object.

Parameters

value	String containing data to encode.
explicitTagging	Flag indicating explicit tagging should be done
tag	Universal tag to apply

Exceptions

Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1BerOutputStream.

References Asn1OctetString._TAG, Asn1BMPString._TAG, Asn1Tag.CONS, Asn1Tag.mClass, and Asn1Tag.mIDCode.

◆ EncodeCharString()

override void EncodeCharString	(	System.String	value,
		bool	explicitTagging,
		Asn1Tag	tag
	)

virtual

This method encodes and writes to the stream an ASN.1 8-bit character string types including IA5String, PrintableString, NumericString, etc. The UNIVERSAL tag value and length is also encoded if explicit tagging is specified (the universal identifier must be provided by the caller).

Throws, exception thrown by the underlying System.IO.Stream object.

Parameters

value	The string object to be written
explicitTagging	Flag indicating explicit tagging should be done
tag	Universal tag to apply

Exceptions

Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1BerOutputStream.

References Asn1Tag.CONS, Asn1Tag.mClass, Asn1Tag.mIDCode, and Asn1Util.ToByteArray().

◆ EncodeOctetString()

override void EncodeOctetString	(	byte []	value,
		bool	explicitTagging,
		Asn1Tag	tag
	)

virtual

This method writes the given array of bytes as octet string value.

Throws, exception thrown by the underlying System.IO.Stream object.

Parameters

value	Byte array containing data to encode.
explicitTagging	Flag indicating explicit tagging should be done
tag	Universal tag to apply

Exceptions

Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1BerOutputStream.

References Asn1OctetString._TAG, Asn1Tag.CONS, Asn1Tag.mClass, and Asn1Tag.mIDCode.

◆ EncodeStringTag() [1/2]

virtual void EncodeStringTag	(	int	nbytes,
		Asn1Tag	tag
	)

virtual

This method encodes and writes both a tag and length value to the stream.

Throws, exception thrown by the underlying System.IO.Stream object.

Parameters

nbytes	The number of bytes in string to be encoded.
tag	The tag to be encoded.

References Asn1Tag.CONS, Asn1Tag.mClass, and Asn1Tag.mIDCode.

◆ EncodeStringTag() [2/2]

virtual void EncodeStringTag	(	int	nbytes,
		short	tagClass,
		short	tagForm,
		int	tagIDCode
	)

virtual

This method encodes and writes both a tag and length value to the stream.

Throws, exception thrown by the underlying System.IO.Stream object.

Parameters

nbytes	The number of bytes in string to be encoded.
tagClass	The class of the tag to be encoded.
tagForm	The form of the tag to be encoded.
tagIDCode	The ID code of the tag to be encoded.

References Asn1Tag.CONS.

◆ EncodeUnivString()

override void EncodeUnivString	(	int []	value,
		bool	explicitTagging,
		Asn1Tag	tag
	)

virtual

This method writes the given array of integers as UniversalString value.

Throws, exception thrown by the underlying System.IO.Stream object.

Parameters

value	Array containing data to encode.
explicitTagging	Flag indicating explicit tagging should be done
tag	Universal tag to apply

Exceptions

Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1BerOutputStream.
