All Known Implementing Classes:

DeterministicKey, DeterministicSeed, ECKey
```
public interface EncryptableItem
```
Provides a uniform way to access something that can be optionally encrypted with a KeyCrypter, yielding an EncryptedData, and which can have a creation time associated with it.

`EncryptedData`	`getEncryptedData()`	Returns the initialization vector and encrypted secret bytes, or null if not encrypted.
`Protos.Wallet.EncryptionType`	`getEncryptionType()`	Returns an enum constant describing what algorithm was used to encrypt the key or UNENCRYPTED.
`byte[]`	`getSecretBytes()`	Returns the raw bytes of the item, if not encrypted, or null if encrypted or the secret is missing.
`boolean`	`isEncrypted()`	Returns whether the item is encrypted or not.

- Method Detail
  - isEncrypted
```
boolean isEncrypted()
```
    Returns whether the item is encrypted or not. If it is, then getSecretBytes() will return null.
  - getSecretBytes
```
@Nullable
byte[] getSecretBytes()
```
    Returns the raw bytes of the item, if not encrypted, or null if encrypted or the secret is missing.
  - getEncryptedData
```
@Nullable
EncryptedData getEncryptedData()
```
    Returns the initialization vector and encrypted secret bytes, or null if not encrypted.
  - getEncryptionType
```
Protos.Wallet.EncryptionType getEncryptionType()
```
    Returns an enum constant describing what algorithm was used to encrypt the key or UNENCRYPTED.
  - creationTime
```
java.util.Optional<java.time.Instant> creationTime()
```
    Returns the time at which this encryptable item was first created/derived, or empty of unknown.
  - getCreationTimeSeconds
```
@Deprecated
default long getCreationTimeSeconds()
```
    Deprecated.
