Method Detail

encrypt

public static void encrypt(java.io.InputStream is,
                           java.io.OutputStream os,
                           CipherKey ck,
                           Callback cb,
                           long size)
                    throws java.io.IOException

This is the public API exposed to encrypt.

Parameters:

is - The input stream that needs to be encrypted.

os - The output stream where the encrypted content of is need to be written.

ck - The CipherKey object. This has to be created by passing the password to CipherKeyGen.getCipherKeyForEncrypt(String keyStr).

cb - Callback object for monitoring the progress.

size - The size of the is stream. When this is passed, the Callback.notifyProgress(long value) will receive the percentage completed. If this is not passed, it will get the number of bytes read and processed.

Throws:

java.io.IOException - IOException is thrown when faced with IO issues during read/write.

decrypt

public static void decrypt(java.io.InputStream is,
                           java.io.OutputStream os,
                           CipherKey ck,

                    throws java.io.IOException,
                           PasswordMismatchException

This is the public API exposed to decrypt.

Parameters:

is - The input stream that needs to be decrypted.

os - The output stream where the decrypted content of is need to be written.

ck - The CipherKey object. This has to be created by passing the password to CipherKeyGen.getCipherKeyForDecrypt(String keyStr).

cb - Callback object for monitoring the progress.

size - The size of the is stream. When this is passed, the Callback.notifyProgress(long value) will receive the percentage completed. If this is not passed, it will get the number of bytes read and processed.

Throws:

PasswordMismatchException - PasswordMismatchException is thrown when the supplied password is wrong.

java.io.IOException - IOException is thrown when faced with IO issues during read/write.
