Parsable
The Parsable interface describes classes that can be parsed from their binary DER representation.

Parse an instance of this class from its binary DER encoded representation.

Encode this object using DER encoding.

getContent()  : mixed
Return the content of this object in a non encoded form.

Returns the length of the whole object (including the identifier and length octets).

Methods

__construct()

public __construct(array<string|int, ASNObject> ...$children) : mixed
Parameters
$children : array<string|int, ASNObject>

the variadic type hint is commented due to https://github.com/facebook/hhvm/issues/4858

Return values
mixed —

__toString()

public __toString() : mixed
Return values
mixed —

addChildren()

public addChildren(array<string|int, mixed> $children) : mixed
Parameters
$children : array<string|int, mixed>
Return values
mixed —

count()

public count([mixed $mode = COUNT_NORMAL ]) : mixed
Parameters
$mode : mixed = COUNT_NORMAL
Return values
mixed —

current()

public current() : mixed
Return values

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
throws
ParserException
Return values
ASNObject —

getBinary()

Encode this object using DER encoding.

public getBinary() : string
