Parsable
Class ASNObject is the base class for all concrete ASN.1 objects.
Table of Contents
Interfaces
- Parsable
- The Parsable interface describes classes that can be parsed from their binary DER representation.
Properties
- $contentLength : mixed
- $nrOfLengthOctets : mixed
Methods
- __toString() : mixed
- fromBinary() : ASNObject
- Parse an instance of this class from its binary DER encoded representation.
- getBinary() : string
- Encode this object using DER encoding.
- getContent() : mixed
- Return the content of this object in a non encoded form.
- getIdentifier() : string
- Returns all identifier octets. If an inheriting class models a tag with the long form identifier format, it MUST reimplement this method to return all octets of the identifier.
- getObjectLength() : mixed
- Returns the length of the whole object (including the identifier and length octets).
- getType() : int
- Return the object type octet.
- getTypeName() : mixed
- Returns the name of the ASN.1 Type of this object.
- calculateContentLength() : int
- Must return the number of octets of the content part.
- getContentLength() : mixed
- getEncodedValue() : string
- Encode the object using DER encoding.
- getNumberOfLengthOctets() : mixed
- parseBinaryIdentifier() : mixed
- parseContentLength() : mixed
- parseIdentifier() : mixed
- setContentLength() : mixed
- createLengthPart() : mixed

Methods
__toString()
public
__toString() : mixed
fromBinary()
Parse an instance of this class from its binary DER encoded representation.
public
static fromBinary(string &$binaryData[, int &$offsetIndex = 0 ]) : ASNObject
Parameters
- $binaryData : string
- $offsetIndex : int = 0
Tags
Return values
ASNObjectgetBinary()
Encode this object using DER encoding.
public
getBinary() : string
Return values
string —the full binary representation of the complete object
getContent()
Return the content of this object in a non encoded form.
public
abstract getContent() : mixed
This can be used to print the value in human readable form.
getIdentifier()
Returns all identifier octets. If an inheriting class models a tag with the long form identifier format, it MUST reimplement this method to return all octets of the identifier.
public
getIdentifier() : string
Tags
Return values
string —Identifier as a set of octets
getObjectLength()
Returns the length of the whole object (including the identifier and length octets).
public
getObjectLength() : mixed
getType()
Return the object type octet.
public
abstract getType() : int
This should use the class constants of Identifier.
Tags
Return values
intgetTypeName()
Returns the name of the ASN.1 Type of this object.
public
getTypeName() : mixed
Tags
calculateContentLength()
Must return the number of octets of the content part.
protected
abstract calculateContentLength() : int
Return values
intgetContentLength()
protected
getContentLength() : mixed
getEncodedValue()
Encode the object using DER encoding.
protected
abstract getEncodedValue() : string
Tags
Return values
string —the binary representation of an objects value
