In the example given, running context turns '257a410' into '257410'. The DNA example below it exhibits the same problem.

Many thanks for your report, Hugo. I use this code from time to time and I totally overlooked this. Have you checked all options that the sample contains?

Hans, I have just checked that these line breakings loose a character in all options.

Hugo, I have just updated the wiki with another way of line breaking SHA sums: https://wiki.contextgarden.net/Wrapping#Line_breaking_with_SHA512_sums It avoids the issue you encountered and it is an easy workaround.
