NAME gov.va.med.crypto.VistaKernelHash
GENERAL DESCRIPTION
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);

COMPONENT/ENTRY POINT COMPONENT DESCRIPTION VARIABLES
decrypt()
public static java.lang.String
decrypt(java.lang.String encryptedText):

Decrypts a string using the same encoding algorithm as the RPC Broker uses.
VARIABLES TYPE VARIABLES DESCRIPTION
encryptedText Input
java.lang.String: The text to decode. Must be
characters between ASCII 32 and 128.
return Output
returns java.lang.String: a decrypted (decoded)
version of the input string.
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.
VARIABLES TYPE VARIABLES DESCRIPTION
normalText Input
java.lang.String normalText: the text to encode. Must
be characters between ASCII 32 and 128.
preventEncryptionsCont Input
boolean
preventEncryptionsContainingCDataSectionBoundaries: if true, the returned
encrypted strings are guaranteed not to contain either "]]>" or "<![CDATA[".
Otherwise, it is possible a returned encryption may conta in those character
sequences.
return Output
returns java.lang.String: an encrypted (encoded)
version of the input string.
throws Output
throws
gov.va.med.crypto.VistaKernelHashCountLimitExceededException: 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.
