Constructor Detail

ProtectionLauncherConfigReader

public ProtectionLauncherConfigReader()

Creates a new instance of reader

ProtectionLauncherConfigReader

public ProtectionLauncherConfigReader(java.lang.String aSecurityAlgorithm,
                                      byte[] aDecryptKeyBytes)

Creates a new instance of reader and initializes it with security algorithm and decrypt key bytes.

Parameters:

aSecurityAlgorithm - security algorithm

aDecryptKeyBytes - byte[] decrypt key bytes

Method Detail

getSecurityProvider

protected SecurityProvider getSecurityProvider()

getSecurityAlgorithm

public java.lang.String getSecurityAlgorithm()

Returns security algorithm to be used to decode ProtectionLauncherConfig's

Returns:

security algorithm

setSecurityAlgorithm

public void setSecurityAlgorithm(java.lang.String aSecurityAlgorithm)

Specifies security algorithm to be used to decode ProtectionLauncherConfig's

Parameters:

aSecurityAlgorithm - resurity algorithm

getDecryptKeyBytes

public byte[] getDecryptKeyBytes()

Returns bytes array that specifies key used to decrypt the ProtectionLauncherConfig.

Returns:

key bytes

setDecryptKeyBytes

public void setDecryptKeyBytes(byte[] aDecryptKeyBytes)

Specifies bytes array that represents key used to decrypt the ProtectionLauncherConfig.

Parameters:

aDecryptKeyBytes - key bytes

setDecryptKeyBytes

public void setDecryptKeyBytes(java.lang.String aDecryptKeyBytes)

Specifies bytes array used to restore the key required to decrypt the the ProtectionLauncherConfig.

Parameters:

aDecryptKeyBytes - decrypt key bytes as String e.g. "1, 23, 45, 23, -1"

isSkipEncryption

public boolean isSkipEncryption()

Checks whether ProtectionLauncherConfig encryption should be skipped.

Returns:

true ProtectionLauncherConfig encryption should be skipped, false otherwise.

setSkipEncryption

public void setSkipEncryption(boolean aSkipEncryption)

Specifies that ProtectionLauncherConfig encryption should be skipped. Note: skipping can be useful for debugging purposes only.

Parameters:

aSkipEncryption - true if ProtectionLauncherConfig encryption should be skipped, false otherwise.

isVerbose

public boolean isVerbose()

Checks whether reader runs in verbose mode.

Returns:

true if reader runs in verbose mode, false otherwise.

setVerbose

public void setVerbose(boolean aVerbose)

Specifies that reader should run in verbose mode. If reader run in verbose mode all thrown exceptions and stack traces will be printed out to the stderr. Otherwise there is no output generated in order to prevent the "code flow" analysis.

Parameters:

aVerbose - true if reader should run in verbose mode, false otherwise.

error

protected void error(java.lang.Throwable aThrowable)

read

public ProtectionLauncherConfig read(java.io.InputStream anInputStream)
                              throws java.io.IOException

Reads and decodes ProtectionLauncherConfig from the specified stream

Parameters:

anInputStream - stream to read ProtectionLauncherConfig from

Returns:

ProtectionLauncherConfig has been read

Throws:

java.io.IOException - in case of reading error

read
