I am interested in generating 8192 bit keys out of curiosity. I know that 4096 bit keys is the maximum key strength that is recommended, but I would like to know how to increase the size. I have tried to modify one of the file's in C and then compile it, but I failed and it did not work. The terminal would try to attempt to generate entropy, but it failed out after about a minute or so. Can someone please guide me how to make GPG key size larger than 4096?
I would appreciate any help. Once again, I understand this is not recommended, but I would really like to know how to do this. Cheers.
