Detailed Description

Implements Signer interface for ID-Cards, which support PKCS#11 protocol.

Abstract method selectSigningCertificate is called if the signer needs to choose the correct signing certificate. It is called also if there is only one certificate found on ID-Card. Parameter certificates provides list of all certificates found in the ID-Card.

Abstract method pin is called if the selected certificate needs PIN to log in.

Constructor & Destructor Documentation

PKCS11Signer()

PKCS11Signer::PKCS11Signer

(

const std::string &

driver = ""

)

Loads PKCS#11 driver.

Parameters

driver

full path to the PKCS#11 driver (e.g. /usr/lib/opensc-pkcs11.so)

Exceptions

Exception

exception is thrown if the provided PKCS#11 driver loading failed.

References digidoc::Conf::instance(), and digidoc::Conf::PKCS11Driver().

~PKCS11Signer()

PKCS11Signer::~PKCS11Signer ( )

override

Unload PKCS#11 module and releases acquired memory.

Member Function Documentation

cert()

X509Cert PKCS11Signer::cert ( ) const

overridevirtual

Reimplemented parent class method digidoc::Signer::cert

Finds all slots connected with the computer, if the slots have tokens, lists all certificates found in token. If there is more that 1 certificate lets the user application select (by calling the selectSignCertificate callback function) the certificate used for signing.

Exceptions

Exception

throws exception if failed to select the signing certificate. For example no cards found or card has no certificate.

Implements digidoc::Signer.

method()

string PKCS11Signer::method ( ) const

overridevirtual

Gets signature method

Reimplemented from digidoc::Signer.

References digidoc::Signer::method().

Referenced by sign().

pin()

string PKCS11Signer::pin ( const X509Cert &  certificate ) const

protectedvirtual

Abstract method that returns PIN code for the selected signing certificate. If PIN code is not needed this method is never called. To cancel the login this method should throw an exception.

Parameters

certificate

certificate that is used for signing and needs a PIN for login.

Returns

returns the PIN code to login.

Exceptions

Exception

should throw an exception if the login operation should be canceled.

Referenced by setPin(), and sign().

selectSigningCertificate()

X509Cert PKCS11Signer::selectSigningCertificate ( const std::vector< X509Cert > &  certificates ) const

protectedvirtual

Abstract method for selecting the correct signing certificate. If none of the certificates suit for signing, this method should throw an Exception. This method is always called, when there is at least 1 certificate available.

Parameters

certificates

available certificates to choose from.

Returns

returns the certificate used for signing.

Exceptions

Exception

should throw an exception if no suitable certificate is in the list or the operation should be cancelled.

Referenced by cert().

setPin()

void PKCS11Signer::setPin

(

const std::string &

pin

)

If sub class does not want reimplement pin method then it is possible set default pin

Parameters

pin

References pin().

sign()

vector< unsigned char > PKCS11Signer::sign ( const std::string &  method, const std::vector< unsigned char > &  digest  ) const

overridevirtual

Reimplemented parent class method digidoc::Signer::sign

Signs the digest provided using the selected certificate. If the certificate needs PIN, the PIN is acquired by calling the callback function pin.

Parameters

method	digest method to be used
digest	digest to sign

Returns

signature signed result

Exceptions

Exception

throws exception if the signing operation failed.

Implements digidoc::Signer.
