Public constructors
PasswordProtection
PasswordProtection(password: CharArray!)
Creates a password parameter.
The specified password is cloned before it is stored in the new PasswordProtection object.
| Parameters | |
|---|---|
password |
CharArray!: the password, which may be null |
PasswordProtection
PasswordProtection(
password: CharArray!,
protectionAlgorithm: String!,
protectionParameters: AlgorithmParameterSpec!)
Creates a password parameter and specifies the protection algorithm and associated parameters to use when encrypting a keystore entry.
The specified password is cloned before it is stored in the new PasswordProtection object.
| Parameters | |
|---|---|
password |
CharArray!: the password, which may be null |
protectionAlgorithm |
String!: the encryption algorithm name, for example, PBEWithHmacSHA256AndAES_256. See the Cipher section in the Java Security Standard Algorithm Names Specification for information about standard encryption algorithm names. |
protectionParameters |
AlgorithmParameterSpec!: the encryption algorithm parameter specification, which may be null |
| Exceptions | |
|---|---|
java.lang.NullPointerException |
if protectionAlgorithm is null |
Public methods
destroy
open fun destroy(): Unit
Clears the password.
| Exceptions | |
|---|---|
javax.security.auth.DestroyFailedException |
if this method was unable to clear the password |
getPassword
open fun getPassword(): CharArray!
Gets the password.
Note that this method returns a reference to the password. If a clone of the array is created it is the caller's responsibility to zero out the password information after it is no longer needed.
| Return | |
|---|---|
CharArray! |
the password, which may be null |
See Also
| Exceptions | |
|---|---|
java.lang.IllegalStateException |
if the password has been cleared (destroyed) |
getProtectionAlgorithm
open fun getProtectionAlgorithm(): String!
Gets the name of the protection algorithm. If none was set then the keystore provider will use its default protection algorithm. The name of the default protection algorithm for a given keystore type is set using the 'keystore.<type>.keyProtectionAlgorithm' security property. For example, the keystore.PKCS12.keyProtectionAlgorithm property stores the name of the default key protection algorithm used for PKCS12 keystores. If the security property is not set, an implementation-specific algorithm will be used.
| Return | |
|---|---|
String! |
the algorithm name, or null if none was set |
getProtectionParameters
open fun getProtectionParameters(): AlgorithmParameterSpec!
Gets the parameters supplied for the protection algorithm.
| Return | |
|---|---|
AlgorithmParameterSpec! |
the algorithm parameter specification, or null, if none was set |
isDestroyed
open fun isDestroyed(): Boolean
Determines if password has been cleared.
| Return | |
|---|---|
Boolean |
true if the password has been cleared, false otherwise |
