DiffieHellmanGroup 类

const name = 'modp1';
const dh = crypto.createDiffieHellmanGroup(name);

name 取自 RFC 2412（modp1 和 2）和 RFC 3526：

$ perl -ne 'print "$1\n" if /"(modp\d+)"/' src/node_crypto_groups.h
modp1  #  768 位
modp2  # 1024 位
modp5  # 1536 位
modp14 # 2048 位
modp15 # 等等。
modp16
modp17
modp18

The DiffieHellmanGroup class takes a well-known modp group as its argument but otherwise works the same as DiffieHellman.

const name = 'modp1';
const dh = crypto.createDiffieHellmanGroup(name);

name is taken from RFC 2412 (modp1 and 2) and RFC 3526:

$ perl -ne 'print "$1\n" if /"(modp\d+)"/' src/node_crypto_groups.h
modp1  #  768 bits
modp2  # 1024 bits
modp5  # 1536 bits
modp14 # 2048 bits
modp15 # etc.

modp17
