Method Details

getAlgorithm

public String getAlgorithm()

Specified by:

getAlgorithm in interface Key

getFormat

public String getFormat()

return the encoding format we produce in getEncoded().

Specified by:

getFormat in interface Key

Returns:

the string "PKCS#8"

getEncoded

public byte[] getEncoded()

Return a PKCS8 representation of the key. The sequence returned represents a full PrivateKeyInfo object.

Specified by:

getEncoded in interface Key

Returns:

a PKCS8 representation of the key.

getParams

public ECParameterSpec getParams()

Specified by:

getParams in interface AsymmetricKey

Specified by:

getParams in interface ECKey

Specified by:

getParams in interface ECPrivateKey

getParameters

public ECParameterSpec getParameters()

Description copied from interface: ECKey

return a parameter specification representing the EC domain parameters for the key.

Specified by:

getParameters in interface ECKey

getS

public BigInteger getS()

Specified by:

getS in interface ECPrivateKey

getD

public BigInteger getD()

Description copied from interface: ECPrivateKey

return the private value D.

Specified by:

getD in interface ECPrivateKey

setBagAttribute

public void setBagAttribute(ASN1ObjectIdentifier oid,
 ASN1Encodable attribute)

Specified by:

setBagAttribute in interface PKCS12BagAttributeCarrier

getBagAttribute

public ASN1Encodable getBagAttribute(ASN1ObjectIdentifier oid)

Specified by:

getBagAttribute in interface PKCS12BagAttributeCarrier

getBagAttributeKeys

public Enumeration getBagAttributeKeys()

Specified by:

getBagAttributeKeys in interface PKCS12BagAttributeCarrier

hasFriendlyName

public boolean hasFriendlyName()

Specified by:

hasFriendlyName in interface PKCS12BagAttributeCarrier

setFriendlyName

public void setFriendlyName(String friendlyName)

Specified by:

setFriendlyName in interface PKCS12BagAttributeCarrier

setPointFormat

public void setPointFormat(String style)

Description copied from interface: ECPointEncoder

Set the formatting for encoding of points. If the String "UNCOMPRESSED" is passed in point compression will not be used. If the String "COMPRESSED" is passed point compression will be used. The default is "UNCOMPRESSED".

Specified by:

setPointFormat in interface ECPointEncoder

Parameters:

style - the style to use.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

destroy

public void destroy()

Destroy this key, clearing the key material it holds.

The private value is held as a BigInteger, which is immutable and so cannot be zeroized in place - destruction drops the internal reference so the value becomes unreachable (cleared on garbage collection). The (public) domain parameters and public key details are retained. After destruction isDestroyed() returns true, the secret-bearing accessors (getEncoded(), getS() and getD()) throw IllegalStateException, the key can no longer be serialized, and it is equal only to itself; hashCode() retains its pre-destruction value.

Specified by:

destroy in interface Destroyable

isDestroyed

public boolean isDestroyed()

Specified by:

isDestroyed in interface Destroyable
