Interface PGPDataEncryptor

All Known Subinterfaces:
PGPAEADDataEncryptor
public interface PGPDataEncryptor
A data encryptor, combining a cipher instance and an optional integrity check calculator.

PGPDataEncryptor instances are generally not constructed directly, but obtained from a PGPDataEncryptorBuilder.

  • Method Summary

    Modifier and Type
    Method
    Description
    int
    getBlockSize()
    Gets the block size of the underlying cipher used by this encryptor.
    PGPDigestCalculator
    getIntegrityCalculator()
    Obtains the integrity check calculator configured for this encryptor instance.
    OutputStream
    getOutputStream(OutputStream out)
    Constructs an encrypting output stream that encrypts data using the underlying cipher of this encryptor.

  • Method Details

    • getOutputStream

      OutputStream getOutputStream(OutputStream out)
      Constructs an encrypting output stream that encrypts data using the underlying cipher of this encryptor.

      The cipher instance in this encryptor is used for all output streams obtained from this method, so it should only be invoked once.

      Parameters:
      out - the stream to wrap and write encrypted data to.
      Returns:
      a cipher output stream appropriate to the type of this data encryptor.

    • getIntegrityCalculator

      PGPDigestCalculator getIntegrityCalculator()
      Obtains the integrity check calculator configured for this encryptor instance.
      Returns:
      the integrity check calculator, or null if no integrity checking was configured.

    • getBlockSize

      int getBlockSize()
      Gets the block size of the underlying cipher used by this encryptor.
      Returns:
      the block size in bytes.
