2 data objects (secret key, ciphertext) from SKEncrypt or SKComputation task

1 data object (data)

Restriction: task must have at exactly two input and one output data objects
Error: exactly 2 inputs and 1 output are required

Restriction: “ciphertext” property must exist under stereotype details object - “ciphertext” must have been selected and saved and “ciphertext” information must not have been deleted from model’s file
Error: ciphertext is undefined

Restriction: “key” property must exist under stereotype details object - “key” must have been selected and saved and “key” information must not have been deleted from model’s file
Error: key is undefined

Restriction: input data object fixed (by its id) in “ciphertext” property must exist also on model
Error: ciphertext object is missing

Restriction: input data object fixed (by its id) in “key” property must exist also on model
Error: key object is missing

Restriction: ciphertext and key objects must be different data objects - they must have different ids
Error: ciphertext and key must be different objects

Restriction: input data object selected as key must be an input object “key” from SKEncrypt task or one of the input objects selected as “Encrypted” from SKComputation task - it must have the same name as input object “key” from SKEncrypt task or as one of the input objects selected as “Encrypted” from SKComputation task
Error: ciphertext is encrypted with wrong encryption method or is not encrypted

Restriction: input data object selected as key must be with the same name as all input “encryption key” objects from SKEncrypt and SKComputation tasks - there must be only one unique key name concerning particular input ciphertext
Error: decryption key must be the same (with the same name) as the encryption key
