Parameters:

encryptionContext - The encryption context.

Returns:

EncryptionMaterials which caller can use to encrypt or decrypt data

getEncryptionMaterials

public abstract EncryptionMaterials getEncryptionMaterials(Map<String,String> materialDescription)

Gets encryption materials by material description. This is used when EMR fetches encryption materials to do decryption. The material description can be any information defined by users that uniquely identifies a encryption material in user's system.

Parameters:

materialDescription - The materials description.
