WebOct 12, 2024 · This causes the KP_IV of the original key to be placed in the duplicate key. After you create or import the original key, you cannot use the original key for encryption because the feedback register of the key will be changed. The following pseudocode shows how this can be done. // Set the IV for the original key. WebNov 28, 2024 · If you wanted to actually use an IV, and you wanted to use the deprecated functions being used in the crypt.au3 UDF, then you would use the CryptSetKeyParam function. In other words, you would have to code that function yourself.
