  • Method Details

    • getBlockSize

      public int getBlockSize()
      Specified by:
      getBlockSize in interface Cipher
      Returns:
      the block size for this cipher

    • getIVSize

      public int getIVSize()
      Specified by:
      getIVSize in interface Cipher
      Returns:
      the size of the initialization vector

    • getAuthenticationTagSize

      public int getAuthenticationTagSize()
      Specified by:
      getAuthenticationTagSize in interface Cipher
      Returns:
      Size of the authentication tag (AT) in bytes or 0 if this cipher does not support authentication

    • init

      public void init(Cipher.Mode mode, byte[] bytes, byte[] bytes1)
      Description copied from interface: Cipher
      Initialize the cipher for encryption or decryption with the given private key and initialization vector
      Specified by:
      init in interface Cipher
      Parameters:
      mode - whether this instance wil encrypt or decrypt
      bytes - the key for the cipher
      bytes1 - initialization vector

    • update

      public void update(byte[] input, int inputOffset, int inputLen)
      Description copied from interface: Cipher
      Performs in-place encryption or decryption on the given data.
      Specified by:
      update in interface Cipher
      Parameters:
      input - the subject
      inputOffset - offset at which to start
      inputLen - number of bytes starting at inputOffset

    • updateAAD

      public void updateAAD(byte[] data, int offset, int length)
      Description copied from interface: Cipher
      Adds the provided input data as additional authenticated data during encryption or decryption.
      Specified by:
      updateAAD in interface Cipher
      Parameters:
      data - The additional data to authenticate
      offset - The offset of the additional data in the buffer
      length - The number of bytes in the buffer to use for authentication

    • updateAAD

      public void updateAAD(byte[] data)
      Description copied from interface: Cipher
      Adds the provided input data as additional authenticated data during encryption or decryption.
      Specified by:
      updateAAD in interface Cipher
      Parameters:
      data - The data to authenticate

    • updateWithAAD

      public void updateWithAAD(byte[] input, int offset, int aadLen, int inputLen)
      Description copied from interface: Cipher
      Performs in-place authenticated encryption or decryption with additional data (AEAD). Authentication tags are implicitly appended after the output ciphertext or implicitly verified after the input ciphertext. Header data indicated by the aadLen parameter are authenticated but not encrypted/decrypted, while payload data indicated by the inputLen parameter are authenticated and encrypted/decrypted.
      Specified by:
      updateWithAAD in interface Cipher
      Parameters:
      input - The input/output bytes
      offset - The offset of the data in the input buffer
      aadLen - The number of bytes to use as additional authenticated data - starting at offset
      inputLen - The number of bytes to update - starting at offset + aadLen

    • setSequenceNumber

      public void setSequenceNumber(long seq)
      Specified by:
      setSequenceNumber in interface Cipher
