As I mentionned yesterday, The same key and crt files works perfectly
and the value of ts.Strings[1] =
'trailer'#$D#$A'<</Size 24/Root 1 0 R/Info 9 0 R/ID[<46BCBBAA531A104F9763C9BF3C787E12>>><46BCBBAA531A104F9763C9BF3C787E12>] >>
and ts.Strings[7] = ' ' (blank)
That is exactly the same string as with my project !!!
