A data-flow node that is an application of a cryptographic algorithm. For example, encryption, decryption, signature-validation.

Extend this class to refine existing API models. If you want to model new APIs, extend CryptographicOperation::Range instead.

Predicates

getAlgorithm

Gets the algorithm used, if it matches a known CryptographicAlgorithm.

getAnInput

Gets an input the algorithm is used on, for example the plain text input to be encrypted.

getBlockMode

Gets the block mode used to perform this cryptographic operation.

getInitialization

Gets the data-flow node where the cryptographic algorithm used in this operation is configured.

Inherited predicates

asCfgNode

Gets the control-flow node corresponding to this node, if any.

from Node
asExpr

Gets the expression corresponding to this node, if any.

from Node
getALocalSource

Gets a local source node from which data may flow to this node in zero or more local data-flow steps.

from Node
getEnclosingCallable

Gets the enclosing callable of this node.

from Node
getLocation

Gets the location of this node

from Node
getScope

Gets the scope of this node.

from Node
