Method Detail

getCipherName

String getCipherName()

Returns:

Basic cipher used to obfuscate

getSupportedKeySizes

List<Integer> getSupportedKeySizes()

Returns:

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

appendPrivateKeyEncryptionContext

<A extends Appendable> A appendPrivateKeyEncryptionContext(A sb,
                                                           PrivateKeyEncryptionContext encContext)
                                                    throws IOException

Type Parameters:

A - Appendable generic type

Parameters:

sb - The Appendable instance to update

encContext -

Returns:

Same appendable instance

Throws:

IOException

generateInitializationVector

byte[] generateInitializationVector(PrivateKeyEncryptionContext encContext)
                             throws GeneralSecurityException

Parameters:

encContext - The encryption context

Returns:

An initialization vector suitable to the specified context

Throws:

GeneralSecurityException

applyPrivateKeyCipher

byte[] applyPrivateKeyCipher(byte[] bytes,
                             PrivateKeyEncryptionContext encContext,
                             boolean encryptIt)
                      throws IOException,
                             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:

IOException - If malformed input

GeneralSecurityException - If cannot encrypt/decrypt
