Method Detail

applyPrivateKeyCipher

public byte[] applyPrivateKeyCipher(byte[] bytes,
                                    PrivateKeyEncryptionContext encContext,
                                    boolean encryptIt)
                             throws GeneralSecurityException

Parameters:

bytes - Original bytes

encContext - The encryption context

encryptIt - If true then encrypt the original bytes, otherwise decrypt them

Returns:

The result of applying the cipher to the original bytes

Throws:

GeneralSecurityException - If cannot encrypt/decrypt

getSupportedKeySizes

public List<Integer> getSupportedKeySizes()

Returns:

A List of the supported key sizes - Note: every call returns a and un-modifiable instance.

resolveKeyLength

protected int resolveKeyLength(PrivateKeyEncryptionContext encContext)
                        throws GeneralSecurityException

Specified by:

resolveKeyLength in class AbstractPrivateKeyObfuscator

Throws:

GeneralSecurityException

generateInitializationVector

protected byte[] generateInitializationVector(int keyLength)

Overrides:

generateInitializationVector in class AbstractPrivateKeyObfuscator

resolveEffectiveContext

public static final PrivateKeyEncryptionContext resolveEffectiveContext(PrivateKeyEncryptionContext encContext)
