Cause
This error occurs when the input contains an encrypted source header that is invalid. An encrypted source header must be the following format.
_encrypted[n]
In this format, n is the number of characters that have been encrypted following the header.
This error can also be returned if there is not a valid _endEncrypted trailer following the encrypted characters. For example, this could occur if the source file has been changed by editing an encrypted source file and removing or inserting carriage return characters.
Action
Verify that the header is in the correct format. If this is the case, check that the source file has not been changed since it was originally extracted.
