Dhe encryption

WebSummary: when talking about DH, a "big" size like 1024 or 3072 normally means "the size of p", while a "small" size like 160 or 256 normally means "the size of q" or "the size of t".There is no standard for "the size", and indeed the standard does not define a unique one-size-fits-all size. In your Wikipedia quote, the "3072 bits" is the size of p (the modulus). WebJul 14, 2024 · What is the Diffie-Hellman key exchange.
