In general, this can be broken down into over-the-wire (cf. SSL/ TLS ) and back-end encryption. While the former is widely used, the latter is rather seldom to find. Different reasons might exits why one wants to encrypt her data, ranging from preserving a competitive advantage to end-user privacy issues. No matter why someone wants to encrypt the data, the question is do systems support ...

HUC is reasonably well documented, if by “reasonably well” you mean “omits any discussion of the relationship between method calls and underlying HTTP traffic”. Let me fill that in. Who knows, maybe some JavaDocs maintainer somewhere will feel inspired ...
