EdECPrivateKeySpec
extends Object
implements
KeySpec
A class representing elliptic curve private keys as defined in
RFC 8032: Edwards-Curve
Digital Signature Algorithm (EdDSA), including the curve and other
algorithm parameters. The private key is a bit string represented using
a byte array. This class only supports bit string lengths that are a
multiple of 8.
Summary
Public methods |
|---|
byte[]
|
getBytes()
Get the byte array representing the private key.
|
NamedParameterSpec
|
getParams()
Get the algorithm parameters that define the curve and other settings.

From class
java.lang.Object
Object
|
clone()
Creates and returns a copy of this object.
|
boolean
|
equals(Object obj)
Indicates whether some other object is "equal to" this one.
|

Public constructors
EdECPrivateKeySpec
public EdECPrivateKeySpec (NamedParameterSpec params,
byte[] bytes)
Construct a private key spec using the supplied parameters and
bit string.
| Parameters |
|---|
params |
NamedParameterSpec: the algorithm parameters. |
bytes |
byte: the key as a byte array. This array is copied
to protect against subsequent modification. |
Public methods
getBytes
public byte[] getBytes ()
Get the byte array representing the private key. A new copy of the array
is returned each time this method is called.
| Returns |
|---|
byte[] |
the private key as a byte array. |
getParams
public NamedParameterSpec getParams ()
Get the algorithm parameters that define the curve and other settings.
