Member Function Documentation

virtual OFBool SiSecurityProfile::attributeForbidden

(

const DcmTagKey &

key

)

const [pure virtual]

checks whether an attribute with the given tag must not be signed for the current security profile.

Parameters:

key	tag key to be checked

Returns:

true if attribute must not be signed, false otherwise.

Implemented in SiNullProfile, and SiBaseRSAProfile.

virtual OFBool SiSecurityProfile::attributeRequired

(

const DcmTagKey &

key

)

const [pure virtual]

checks whether an attribute with the given tag is required to be signed for the current security profile.

Parameters:

key	tag key to be checked

Returns:

true if required, false otherwise.

Implemented in SiNullProfile, SiBaseRSAProfile, SiAuthorizationProfile, and SiCreatorProfile.

virtual OFBool SiSecurityProfile::checkAttributeList	(	DcmItem &	item,
		DcmAttributeTag &	tagList
	)		[virtual]

checks whether the given list of attribute tags fulfils the requirements of the current security profile for the given dataset.

Parameters:

item	dataset to be checked
tagList	attribute tag list.

Returns:

true if minimum requirements for profile are fulfilled, false otherwise.

static OFBool SiSecurityProfile::containsTag	(	DcmAttributeTag &	tagList,
		const DcmTagKey &	key
	)		[static]

checks if the given tag key is contained in the given list.

Parameters:

tagList	list of tag keys
key	tag key

Returns:

true if tag key is present in list, false otherwise.

virtual OFBool SiSecurityProfile::isAllowableAlgorithm

(

const SiAlgorithm &

algo

)

const [virtual]

checks whether the given public/private key object can be used with this security profile.

Parameters:

algo	object to be checked

Returns:

true if object is allowable for this profile, false otherwise.

virtual OFBool SiSecurityProfile::isAllowableAlgorithmType

(

E_KeyType

keyType

)

const [pure virtual]

checks whether the given public/private key algorithm can be used with this security profile.

Parameters:

keyType

public key algorithm type to be checked

Returns:

true if public key algorithm is allowable for this profile, false otherwise.

Implemented in SiNullProfile, and SiBaseRSAProfile.

virtual OFBool SiSecurityProfile::isAllowableMAC

(

const SiMAC &

mac

)

const [virtual]

checks whether the given MAC object can be used with this security profile.

Parameters:

macType

object to be checked

Returns:

true if object is allowable for this profile, false otherwise.

virtual OFBool SiSecurityProfile::isAllowableMACType

(

E_MACType

macType

)

const [pure virtual]

checks whether the given MAC type can be used with this security profile.

Parameters:

macType

MAC type to be checked

Returns:

true if MAC type is allowable for this profile, false otherwise.

Implemented in SiNullProfile, and SiBaseRSAProfile.

virtual OFBool SiSecurityProfile::isAllowableTransferSyntax

(

E_TransferSyntax

xfer

)

const [pure virtual]

checks whether the given transfer syntax can be used with this security profile

Parameters:

xfer	transfer syntax to be checked

Returns:

true if transfer syntax is allowable for this profile, false otherwise.

Implemented in SiNullProfile, and SiBaseRSAProfile.

virtual OFCondition SiSecurityProfile::updateAttributeList	(	DcmItem &	item,
		DcmAttributeTag &	tagList
	)		[virtual]

updates the given list of attribute tags according to the requirements of the current security profile.

For all elements present in the dataset, the attribute tag is inserted or removed from the list if required by the profile.

Parameters:

item	dataset to be handled
tagList	attribute tag list to be updated

Returns:

status code
