Methods

__construct

public __construct(mixed $v = false): mixed

Parameters:

Parameter	Type	Description
$v	mixed

---

setParent

public setParent(mixed $parent): mixed

Parameters:

Parameter	Type	Description
$parent	mixed

---

generateSubclasses

This function will take the markers and types arrays and dynamically generate classes that extend this class for each one, and also define constants for them.

public static generateSubclasses(): mixed

• This method is static.

---

makeSubclass

Helper function for generateSubclasses()

public static makeSubclass(mixed $name, mixed $bit): mixed

• This method is static.

Parameters:

Parameter	Type	Description
$name	mixed
$bit	mixed

---

reset

This function reset's the internal cursor used for value iteration.

public reset(): mixed

---

__get

This function catches calls to get the value for the type, typeName, value, values, and data from the object. For type calls we just return the class name or the value of the constant that is named the same as the class.

public __get(mixed $name): mixed

Parameters:

Parameter	Type	Description
$name	mixed

---

parseASNString

Parse an ASN.1 binary string.

public static parseASNString(string $string = false, int $level = 1, mixed $maxLevels = false): \ASN_BASE

This function takes a binary ASN.1 string and parses it into it's respective pieces and returns it. It can optionally stop at any depth.

• This method is static.

Parameters:

Parameter	Type	Description
$string	string	The binary ASN.1 String
$level	int	The current parsing depth level
$maxLevels	mixed

Return Value:

The array representation of the ASN.1 data contained in $string

---

parseASNData

Parse an ASN.1 field value.

public static parseASNData(int $type, string $data, int $level, int $maxLevels): mixed

This function takes a binary ASN.1 value and parses it according to it's specified type

• This method is static.

Parameters:

Parameter	Type	Description
$type	int	The type of data being provided
$data	string	The raw binary data string
$level	int	The current parsing depth
$maxLevels	int	The max parsing depth

Return Value:

The data that was parsed from the raw binary data string

---

parseOID

Parse an ASN.1 OID value.

public static parseOID(mixed $string): string

This takes the raw binary string that represents an OID value and parses it into its dot notation form. example - 1.2.840.113549.1.1.5 look up OID's here: http://www.oid-info.com/ (the multi-byte OID section can be done in a more efficient way, I will fix it later)

• This method is static.

Parameters:

Parameter	Type	Description
$string	mixed

Return Value:

The OID contained in $data

---

printASN

public static printASN(mixed $x, mixed $indent = ''): mixed

• This method is static.

Parameters:

Parameter	Type	Description
$x	mixed
$indent	mixed
