    • setSizeExtra

      public void setSizeExtra(int sizeExtra)

    • getCipherAlgorithm

      public CipherAlgorithm getCipherAlgorithm()

    • setCipherAlgorithm

      public void setCipherAlgorithm(CipherAlgorithm cipherAlgorithm)

    • getHashAlgorithm

      public HashAlgorithm getHashAlgorithm()

    • setHashAlgorithm

      public void setHashAlgorithm(HashAlgorithm hashAlgorithm)

    • getKeySize

      public int getKeySize()

    • setKeySize

      public void setKeySize(int keyBits)
      Sets the keySize (in bits). Before calling this method, make sure to set the cipherAlgorithm, as the amount of keyBits gets validated against the list of allowed keyBits of the corresponding cipherAlgorithm
