Okteta is a simple editor for the raw data of files.
The data is displayed in two variants: as the numeric values of the bytes and as the character assigned to the values. Values and characters can be shown either in two columns (the traditional display in hex editors) or in rows with the value on top of the character. Editing can be done both for the values and for the characters.
Besides the usual editing capabilities Okteta also brings a small set of tools, like a table listing decodings into common simple data types, a table listing all possible bytes with their character and value equivalents, an info view with a statistic, a checksum calculator, a filter tool and a string extraction tool.
All modifications to the data loaded can be endlessly undone or redone.
