To summarise the inferred times, it would be:
* 3 weeks up to a month to generate gibberish
* up to around a season to encipher some text (assuming you already had the underlying text)
* when copying faithfully, I found an estimate of around 2 pages a day for a good scribe; that comes out to around 5 months or maybe half a year. This would be assuming the scribe knew the language, though. A faithful rendition if you don't might take longer. (this also assumes an existing draft). This rough speed is somewhat confirmed by a comment on a post my friend found of someone who does calligraphy using archaic methods for fun.
So enciphering takes 3-4 times as long as gibberish, and then a faithful copy takes a little less than double of that, or 6-8 times longer than gibberish.
