类:DiffieHellmanGroup
¥Class: DiffieHellmanGroup
DiffieHellmanGroup
类以著名的 modp 组为参数。它的工作原理与 DiffieHellman
相同,不同之处在于它不允许在创建后更改其密钥。换句话说,它没有实现 setPublicKey()
或 setPrivateKey()
方法。
¥The DiffieHellmanGroup
class takes a well-known modp group as its argument.
It works the same as DiffieHellman
, except that it does not allow changing
its keys after creation. In other words, it does not implement setPublicKey()
or setPrivateKey()
methods.
const { createDiffieHellmanGroup } = await import('node:crypto');
const dh = createDiffieHellmanGroup('modp16');
const { createDiffieHellmanGroup } = require('node:crypto');
const dh = createDiffieHellmanGroup('modp16');
支持以下组:
¥The following groups are supported:

以下组仍受支持但已弃用(请参阅 注意事项):
¥The following groups are still supported but deprecated (see Caveats):
-
'modp1'
(768 位,RFC 2409 第 6.1 节)¥
'modp1'
(768 bits, RFC 2409 Section 6.1) -
'modp2'
(1024 位,RFC 2409 第 6.2 节)¥
'modp2'

'modp5'
(1536 位,RFC 3526 第 2 部分)¥
'modp5'

这些已弃用的组可能会在 Node.js 的未来版本中被删除。
¥These deprecated groups might be removed in future versions of Node.js.
