HMAC SHA256十六进制消息中的一个字符串在Erlang,怎么样? [英] HMAC SHA256 hex digest of a string in Erlang, how?
问题描述
我正在尝试与第三方实时Web消息系统进行交互,由 Pusher.com 的。现在,我不能通过API发送任何东西,除非我生成一个我的数据的 HMAC SHA256十六进制摘要
。用 ruby
编写的示例源代码可以尝试说明这一点:
I am trying to interact with third party real time Web messaging System created and maintained by Pusher.com. Now, i cannot send anything through the API unless i produce an HMAC SHA256 hex digest
of my data. A sample source code written in ruby
could try to illustrate this:
# Dependencies
# gem install ruby-hmac
#
require 'rubygems'
require 'hmac-sha2'
secret = '7ad3773142a6692b25b8'
string_to_sign = "POST\n/apps/3/channels/test_channel/events\nauth_key=278d425bdf160c739803&auth_timestamp=1272044395&auth_version=1.0&body_md5=7b3d404f5cde4a0b9b8fb4789a0098cb&name=foo"
hmac = HMAC::SHA256.hexdigest(secret, string_to_sign)
puts hmac
# >> 309fc4be20f04e53e011b00744642d3fe66c2c7c5686f35ed6cd2af6f202e445
我检查了一个href =http://www.erlang.org/doc/apps/crypto/index.html =nofollow noreferrer> erlang加密库 ,我甚至不能生成一个 SHA256十六进制摘要
直接
我如何在Erlang做这件事? 帮助....
*更新*
我在这里找到了解决方案: 在erlang中的sha256加密 ,他们导致我进入 erlsha2 。但是,如何从该模块生成 SHA256 hexdigest
输出的 HMAC
I checked the erlang crypto Library and i cannot even generate a SHA256 hex digest
"directly"
How do i do this whole thing in Erlang ? help....
* UPDATE *
I have found solutions here: sha256 encryption in erlang and they have led me to erlsha2. But still, how do i generate the HMAC
of a SHA256 hexdigest
output from this module ?
推荐答案
使用 erlsha2 ,使用以下内容获得相当于您的Ruby代码:
With erlsha2, use the following to get the equivalent of your Ruby code:
1> hmac:hexlify(hmac:hmac256(<<"7ad3773142a6692b25b8">>, <<"POST\n/apps/3/channels/test_channel/events\nauth_key=278d425bdf160c739803&auth_timestamp=1272044395&auth_version=1.0&body_md5=7b3d404f5cde4a0b9b8fb4789a0098cb&name=foo">>)).
