Methods

__construct() : void

Constructor (disabled)

_encodeValue(string $data, \const $type) : string

static

Encode a limited set of data types into ASN.1 encoding format which is used in X.509 certificates

Parameters

Name	Type	Description
$data	string	The data to encode
$type	\const	The encoding format constant

Returns

Type	Description
string	The encoded value

Throws

Exception	Description
\Zend_InfoCard_Xml_Security_Exception

_getPublicKeyFromModExp(string $modulus, string $exponent) : string

static

Transform an RSA Key in Modulus/Exponent format into a PEM encoding and return an openssl resource for it

Parameters

Name	Type	Description
$modulus	string	The RSA Modulus in binary format
$exponent	string	The RSA exponent in binary format

Returns

Type	Description
string	The PEM encoded version of the key

_secureStringCompare(string $a, string $b) : bool

static

Securely compare two strings for equality while avoided C level memcmp() optimisations capable of leaking timing information useful to an attacker attempting to iteratively guess the unknown string (e.g.

password) being compared against.

Parameters

Name	Type	Description
$a	string
$b	string

Returns

Type	Description
bool

validateXMLSignature(string $strXMLInput) : bool

static

Validates the signature of a provided XML block

Parameters

Name	Type	Description
$strXMLInput	string	An XML block containing a Signature

Returns

Type	Description
bool	True if the signature validated, false otherwise

Throws

Exception	Description
