I'm evaluating encryption support using encryption contexts. The use case is a table with a single encryption context. I created a table extended from Task then created a field of type "Encrypted Text". As the documentation states, an Encrypted Field Configuration record was automatically created. However it was created with Method = Multiple Encryption Contexts. It was my intent to for it to be a Single Encryption Context method. I see no way to modify (nor delete) this Encrypted Field Configuration record. There is no data in this table.
I can add an Encrypted Field Configuration record for an existing string type field for the same table and select Single Encryption context. So an alternative is to create that new field as a String then apply encryption via Encrypted Field Configuration.
Two questions:
1. Is there a way to change the method from Multiple to Single Encryption Context on the Field Encryption Configuration record?
2. What is the difference between an Ecrypted Text field and a String field that is added to the Encrypted Field Configuration?
