Hi, you can generate the DH prime with the command: openssl dhparam -out <filename> -outform <DER|PEM> -rand <randomnumberseedfile> (-2 | -5) -text -c <dhlength in bits> <randomnumberseed file>: a file to seed openssl's PRNG (-2|-5) : the dh generator (see DH algorithem). 2 is default. -text : extra text output on stdout -c : extra c-variable output on stdout. For example: openssl dhparam -out dh1024.pem 1024 This will generate a dh prime with generator 2 and a length of 1024 bit in dh1024.pem .
