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 SiBaseRSAProfile, and SiNullProfile.

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 SiAuthorizationProfile, SiBaseRSAProfile, SiCreatorProfile, and SiNullProfile.

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 SiBaseRSAProfile, and SiNullProfile.

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 SiBaseRSAProfile, and SiNullProfile.

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 SiBaseRSAProfile, and SiNullProfile.

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
