  • Method Details

    • getFormat

      public String getFormat()
      return the encoding format we produce in getEncoded().
      Specified by:
      getFormat in interface Key
      Overrides:
      getFormat in class JCERSAPrivateKey
      Returns:
      the encoding format we produce in getEncoded().

    • 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
      Overrides:
      getEncoded in class JCERSAPrivateKey
      Returns:
      a PKCS8 representation of the key.

    • getPublicExponent

      public BigInteger getPublicExponent()
      return the public exponent.
      Specified by:
      getPublicExponent in interface RSAPrivateCrtKey
      Returns:
      the public exponent.

    • getPrimeP

      public BigInteger getPrimeP()
      return the prime P.
      Specified by:
      getPrimeP in interface RSAPrivateCrtKey
      Returns:
      the prime P.

    • getPrimeQ

      public BigInteger getPrimeQ()
      return the prime Q.
      Specified by:
      getPrimeQ in interface RSAPrivateCrtKey
      Returns:
      the prime Q.

    • getPrimeExponentP

      public BigInteger getPrimeExponentP()
      return the prime exponent for P.
      Specified by:
      getPrimeExponentP in interface RSAPrivateCrtKey
      Returns:
      the prime exponent for P.

    • getPrimeExponentQ

      public BigInteger getPrimeExponentQ()
      return the prime exponent for Q.
      Specified by:
      getPrimeExponentQ in interface RSAPrivateCrtKey
      Returns:
      the prime exponent for Q.

    • getCrtCoefficient

      public BigInteger getCrtCoefficient()
      return the CRT coefficient.
      Specified by:
      getCrtCoefficient in interface RSAPrivateCrtKey
      Returns:
      the CRT coefficient.

    • 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 JCERSAPrivateKey
      Returns:
      this object's hash code.
      See Also:
      Object.equals(java.lang.Object)

    • 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 JCERSAPrivateKey
      Parameters:
      o - the object to compare this instance with.
      Returns:
      true if the specified object is equal to this Object; false otherwise.

      Object.hashCode()

    • 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.
