Member Function Documentation

createNewKeyPair()

TYPO3 CMS Rsaauth Keypair null TYPO3\CMS\Rsaauth\Backend\PhpBackend::createNewKeyPair

(

)

Creates a new key pair for the encryption or gets the existing key pair (if one already has been generated).

There should only be one key pair per request because the second private key would overwrites the first private key. So the submitting the form with the first public key would not work anymore.

Returns

‪\TYPO3\CMS\Rsaauth\Keypair|null a key pair or NULL in case of error

Reimplemented from TYPO3\CMS\Rsaauth\Backend\AbstractBackend.

decrypt()

string null TYPO3\CMS\Rsaauth\Backend\PhpBackend::decrypt	(		$privateKey,
			$data
	)

Decrypts data using the private key. This implementation uses PHP OpenSSL extension.

Parameters

string	$privateKey	‪The private key (obtained from a call to createNewKeyPair())
string	$data	‪Data to decrypt (base64-encoded)

Returns

‪string|null Decrypted data or NULL in case of an error

extractExponent()

int TYPO3\CMS\Rsaauth\Backend\PhpBackend::extractExponent (   $data )

protected

Extracts the exponent from the OpenSSL CSR

Parameters

string

$data

‪The result of openssl_csr_export()

Returns

‪int The exponent as a number

extractPublicKeyModulus()

string TYPO3\CMS\Rsaauth\Backend\PhpBackend::extractPublicKeyModulus (   $data )

protected

Extracts public key modulus from the OpenSSL CSR.

Parameters

string

$data

‪The result of openssl_csr_export()

Returns

‪string Modulus as uppercase hex string

isAvailable()

bool TYPO3\CMS\Rsaauth\Backend\PhpBackend::isAvailable

(

)

Checks if this backend is available for calling. In particular checks if PHP OpenSSl extension is installed and functional.

Returns

‪bool
