* Correctly enables TLS only during retry grab when retry-tls flag is set.
* Fixes evaluation which caused too many arguments error in IPP integration test.
* Updates IPP zgrab2 schema to reflect storing all attributes in response.
* Adds Attributes member to ScanResults
* Ensures tryReadAttributes only reads attributes in the case of a postive detection. Cleans up isIPP
* Reads all attributes in IPP response
* Detects invalid length errors when reading IPP attributes.
* Returns the correct amount of uris, ipp versions, and cups versions in ScanResults.
* Implement timeout as a float value vs int
* remove unnecessary second multiplier
* whoops, missed one
* Switch type to time.Duration
* Fixup integration tests, change default and description
* Whoops, bad merge
* fix build
* Refactors sending IPP request and handling errors thereof into sendIPPRequest()
* Adds dependency of IPP zgrab2 schema on HTTP zgrab2 schema.
* Refactors out trying to grab with multiple versions into re-usable function.
* Determines whether to output nil result in a concise and accurate manner.
* Refactors reading attributes present in IPP response to its own function. Calls that in Grab and augmentWithCUPSData. Formats code using Go fmt.
* Rejects successful non-IPP responses with protocol error. Reports HTTP errors.
* Removes circular dependency upon http zgrab2 schema.
* Changes name of objects to make IPP schema actually work.
* Changes grab to return *ScanResults. Implements ippInContentType correctly.
* Slots in an operational re-working of several HTTP module functions, and adds dependency on zgrab's http module. Includes some laregly copy-pasted sections worthy of scrutiny.
* Adds support to retry failed HTTP over HTTPS. Removes vestigial functions.
* Implements sending CUPS-get-printers request if CUPS is detected, yielding more detailed & accurate version information. Also handles URI's more correctly.
* Creates separate container to run IPP over TLS on CUPS. Runs basic tests against both containers.
* Creates virtual printer on each container to test for augmenting data with CUPS-get-printers request (which only works when printers exist).
* Augments version information with CUPS-get-printers response if possible.
* Allows specifying IPP version in constructed requests. Checks for version-not-supported server error.
* Allows resending IPP requests with different versions if we hit a version-not-supported error.
* Updates IPP zgrab2 schema to include fields added in modules/ipp/scanner.go
* Removes unnecessary TODO's
* Updates testable example for new definition of AttributeByteString
* Removes versionNotSupported's dependency on bufferFromBody. Checks bounds on generated requests' fields correctly.
* Updates zgrab2 IPP schema to match ScanResults object in modules/ipp/scanner.go
* Corrects IPP tests, bounds checking, zgrab schema formatting.
* Logs errors for unexpected behavior in buffer io operations. Updates schema to include standalone fields for attributes described in CUPS-get-printers response.
* Logs at debug level only when verbose flag is set. Prints accurate error message when CUPSVersion test fails.
* Handles HTTP request errors before checking for nil response/body. Fixes and tests convertURIToIPP.
