I know the idea that students who need to solve their assignment usually put questions here ... But I'm not solving an assignment.
I asked if this is possible?
all what I need is; to generate a watermark sequence with secret key I found through googling that someone was saying to convert string into its ASCII and generate random sequence, but that doesnt generate the same sequence every-time ...
I'm just searching how to make a watermark sequence with secret Key and fixed length where I can regenerate every-time & usually what is used is a pseudo-random noise in this case but I don't know how to make it.
so if anyone can help or suggest something, or explain to me what I seem don't understand, I'll appreciate his help
