What storage methods does Salesforce use to store Master Encryption Keys? For example, are the master keys stored in some type of secure key store? If so, what methods does it use to ensure the keys are secured?
To clarify, I am looking for information on how the actual encryption keys themselves are being securely being stored, not methods on storing information in Salesforce using encrypted fields. The difference is the Master Encryption Keys are used to encrypt the information in the encrypted fields. The Master Encryption Keys can be managed by going to:
Setup > Security Controls > Certificate and Key Management
