Class Cryptography::CryptographicOperation

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.

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. This may have no result - for example if the `CryptographicAlgorithm` used is a stream cipher rather than a block cipher.

asCallable	Gets the callable corresponding to this block, lambda expression, or call to `proc` or `lambda`.	from Node
asExpr	Gets the expression corresponding to this node, if any.	from Node
asParameter	Gets the parameter 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
getAPredecessor	Gets a data flow node from which data may flow to this node in one local step.	from Node
getASuccessor	Gets a data flow node to which data may flow from this node in one local step.	from Node
getConstantValue	Gets the constant value of this expression, if any.	from Node
getLocation	Gets the location of this node.	from Node
hasLocationInfo	Holds if this element is at the specified location. The location spans column `startcolumn` of line `startline` to column `endcolumn` of line `endline` in file `filepath`. For more information, see Locations.	from Node
toString	Gets a textual representation of this node.	from Node
