Method Detail

getEncryptionMaterials

public EncryptionMaterials getEncryptionMaterials()

Description copied from interface: EncryptionMaterialsProvider

Returns EncryptionMaterials which the caller can use for encryption. Each implementation of EncryptionMaterialsProvider can choose its own strategy for loading encryption material. For example, an implementation might load encryption material from an existing key management system, or load new encryption material when keys are rotated.

Specified by:

getEncryptionMaterials in interface EncryptionMaterialsProvider

Returns:

EncryptionMaterials which the caller can use to encrypt or decrypt data.

refresh

public void refresh()

Description copied from interface: EncryptionMaterialsProvider

Forces this encryption materials provider to refresh its encryption material. For many implementations of encryption materials provider, this may simply be a no-op, such as any encryption materials provider implementation that vends static/non-changing encryption material. For other implementations that vend different encryption material throughout their lifetime, this method should force the encryption materials provider to refresh its encryption material.

Specified by:

refresh in interface EncryptionMaterialsProvider

getEncryptionMaterials

public EncryptionMaterials getEncryptionMaterials(Map<String,String> materialsDescription)

Description copied from interface: EncryptionMaterialsAccessor

Retrieves encryption materials matching the specified description from some source.

Specified by:

getEncryptionMaterials in interface EncryptionMaterialsAccessor

Parameters:

materialsDescription - A Map whose key-value pairs describe an encryption materials object

Returns:

The encryption materials that match the description, or null if no matching encryption materials found.
