    - #### RSAPublicKey

          public RSAPublicKey​(java.math.BigInteger modulus,
                              java.math.BigInteger publicExponent)

  - ### Method Detail

    - #### getInstance

          public static RSAPublicKey getInstance​(ASN1TaggedObject obj,
                                                 boolean explicit)

    - #### getInstance

          public static RSAPublicKey getInstance​(java.lang.Object obj)

    - #### getModulus

          public java.math.BigInteger getModulus()

    - #### getPublicExponent

          public java.math.BigInteger getPublicExponent()

    - #### toASN1Primitive

          public ASN1Primitive toASN1Primitive()

      This outputs the key in PKCS1v2 format.
