setEncryptionRequired

Added in API level 18
KeyStoreParameter.Builder setEncryptionRequired (boolean required)

Sets whether this KeyStore entry must be encrypted at rest. Encryption at rest will protect the entry with the secure lock screen credential (e.g., password, PIN, or pattern).

Note that enabling this feature requires that the secure lock screen (e.g., password, PIN, pattern) is set up, otherwise setting the KeyStore entry will fail. Moreover, this entry will be deleted when the secure lock screen is disabled or reset (e.g., by the user or a Device Administrator). Finally, this entry cannot be used until the user unlocks the secure lock screen after boot.

Parameters
required boolean
Returns
KeyStoreParameter.Builder
