Class VistaKernelHash
java.lang.Object

+--gov.va.med.foundations.utilities.VistaKernelHash
- public class VistaKernelHash
- extends java.lang.Object
Implements static methods to provide the encoding algorithms used by the RPC Broker and
Kernel to encode and decode data strings. Using these algorithms makes it harder to sniff
the contents of text sent over the network. This is not, however, encryption-class encoding, nor does it protect
against replay attacks of un-decoded strings, and therefore use of this algorithm should not be considered
to imply or achieve any particular level of security.
For example:
String encodedString = VistaKernelHash.encrypt("some text to encode", true);

VistaKernelHash
public VistaKernelHash()
encrypt
public static java.lang.String encrypt(java.lang.String normalText,
boolean preventEncryptionsContainingCDataSectionBoundaries)
throws VistaKernelHashCountLimitExceededException
- Encrypts a string using the same encoding algorithm as the RPC Broker uses.
- Parameters:
normalText
- the text to encodepreventEncryptionsContainingCDataSectionBoundaries
- if true, the returned encrypted strings are guaranteed
not to contain either "]]>" or "<![CDATA[". Otherwise, it is possible a returned encryption may contain
those character sequences.
- Returns:
- an encrypted (encoded) version of the input string
- Throws:
VistaHashCountLimitExceededException
- if requested that the method not return a result with CData section
boundaries, and if the algorithm runs up to a count limit (presently 2000 tries) without generating a result
without such boundaries, an exception is thrown.
VistaKernelHashCountLimitExceededException
decrypt
public static java.lang.String decrypt(java.lang.String encryptedText)
- Decrypts a string using the same encoding algorithm as the RPC Broker uses.
- Parameters:
encryptedText
- the text to decode
- Returns:
- a decrypted (decoded) version of the input string.
