    • getAlgorithm

      public String getAlgorithm()
      Description copied from interface: Key
      Returns the name of the algorithm of this key. If the algorithm is unknown, null is returned.
      Specified by:
      getAlgorithm in interface Key
      Returns:
      the name of the algorithm of this key or null if the algorithm is unknown.

    • 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()
      Description copied from interface: ECKey
      Returns the EC key parameters.
      Specified by:
      getParams in interface ECKey
      Returns:
      the EC key parameters.

    • 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()
      Description copied from interface: ECPrivateKey
      Returns the private value S.
      Specified by:
      getS in interface ECPrivateKey
      Returns:
      the private value S.

    • 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

    • 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)
      Description copied from class: Object
      Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

      The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

      The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

      Overrides:
      equals in class Object
      Parameters:
      o - the object to compare this instance with.
      Returns:
      true if the specified object is equal to this Object; false otherwise.
      See Also:
      Object.hashCode()

    • hashCode

      public int hashCode()
      Description copied from class: Object
      Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

      Note that hash values must not change over time unless information used in equals comparisons also changes.

      See Writing a correct hashCode method if you intend implementing your own hashCode method.

      Overrides:
      hashCode in class Object
      Returns:
      this object's hash code.
      See Also:
      Object.equals(java.lang.Object)

    • toString

      public String toString()
      Description copied from class: Object
      Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 
         getClass().getName() + '@' + Integer.toHexString(hashCode())

      See Writing a useful toString method if you intend implementing your own toString method.

      Overrides:
      toString in class Object
      Returns:
      a printable representation of this object.
