Detailed Description

template<typename T>
class keypop::calypso::crypto::legacysam::transaction::SignatureComputationData< T >

Contains the input/output data of the FreeTransactionManager#prepareComputeSignature(SignatureComputationData) method for common signature computation modes.

Parameters

<T>	The type of the lowest level child object.

Since

0.1.0

Member Function Documentation

getSignature()

template<typename T >

const std::vector< uint8_t > & keypop::calypso::crypto::legacysam::transaction::SignatureComputationData< T >::getSignature ( ) const

pure virtual

Returns the computed signature.

Returns

A byte array of 1 to 8 bytes.

Exceptions

IllegalStateException

If the command has not yet been processed.

Since

0.1.0

setData()

template<typename T >

virtual T & keypop::calypso::crypto::legacysam::transaction::SignatureComputationData< T >::setData ( const std::vector< uint8_t > &  data, const uint8_t  kif, const uint8_t  kvc  )

pure virtual

Sets the data to be signed and the KIF/KVC of the key to be used for the signature computation.

Parameters

data	The data to be signed.
kif	The KIF of the key to be used for the signature computation.
kvc	The KVC of the key to be used for the signature computation.

Returns

The current instance.

Since

0.1.0

setKeyDiversifier()

template<typename T >

virtual T & keypop::calypso::crypto::legacysam::transaction::SignatureComputationData< T >::setKeyDiversifier ( const std::vector< uint8_t > &  diversifier )

pure virtual

Sets a specific key diversifier to use before signing (optional).

By default, the key diversification is performed with the full serial number of the target card or SAM depending on the transaction context (Card or SAM transaction).

Parameters

diversifier

The diversifier to be used (from 1 to 8 bytes long).

Returns

The current instance.

Since

0.1.0

setSignatureSize()

template<typename T >

virtual T & keypop::calypso::crypto::legacysam::transaction::SignatureComputationData< T >::setSignatureSize ( const int  size )

pure virtual

Sets the expected size of the signature in bytes, which can be between 1 and 8 bytes (optional).

By default, the signature will be generated on 8 bytes.

Note: the longer the signature, the more secure it is.

Parameters

size	The expected size [1..8]

Returns

The current instance.

Since

0.1.0
