    Constructor and Description
    `RSAPublicKey(java.math.BigInteger modulus, java.math.BigInteger publicExponent)`

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `static RSAPublicKey` | `getInstance(ASN1TaggedObject obj, boolean explicit)`
    `static RSAPublicKey` | `getInstance(java.lang.Object obj)`
    `java.math.BigInteger` | `getModulus()`

    - #### 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
