Method Detail

getCipherName

java.lang.String getCipherName()

Returns:

Basic cipher used to obfuscate

getSupportedKeySizes

java.util.List<java.lang.Integer> getSupportedKeySizes()

Returns:

appendPrivateKeyEncryptionContext

<A extends java.lang.Appendable> A appendPrivateKeyEncryptionContext(A sb,
                                                                     PrivateKeyEncryptionContext encContext)
                                                              throws java.io.IOException

Type Parameters:

A - Appendable generic type

Parameters:

sb - The Appendable instance to update

encContext -

Returns:

Same appendable instance

Throws:

java.io.IOException

generateInitializationVector

byte[] generateInitializationVector(PrivateKeyEncryptionContext encContext)
                             throws java.security.GeneralSecurityException

Parameters:

encContext - The encryption context

Returns:

An initialization vector suitable to the specified context

Throws:

java.security.GeneralSecurityException

applyPrivateKeyCipher

byte[] applyPrivateKeyCipher(byte[] bytes,
                             PrivateKeyEncryptionContext encContext,
                             boolean encryptIt)
                      throws java.io.IOException,
                             java.security.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:

java.io.IOException - If malformed input

java.security.GeneralSecurityException - If cannot encrypt/decrypt
