生成HMAC SHA256签名Powershell

Question

对于3逗号，我尝试使用文档中的示例参数在Powershell中生成HMAC SHA256签名：

$secret = 'NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j'
$message = '/public/api/ver1/accounts/new?type=binance&name=binance_account&api_key=XXXXXX&secret=YYYYYY'

$hmacsha = New-Object System.Security.Cryptography.HMACSHA256
$hmacsha.key = [Text.Encoding]::ASCII.GetBytes($secret)
$signature = $hmacsha.ComputeHash([Text.Encoding]::ASCII.GetBytes($message))
$signature = [Convert]::ToBase64String($signature)

$signature

它生成“ MPZ4oVcjApDgBHXP / 8y8kq42WdlMFFosDp0Poo9BwRo =“

作为described in the documentation，它应生成“ 30f678a157230290e00475cfffccbc92ae3659d94c145a2c0e9d0fa28f41c11a”

[linux]$ echo -n "/public/api/ver1/accounts/new?type=binance&name=binance_account&api_key=XXXXXX&secret=YYYYYY" | openssl dgst -sha256 -hmac "NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j"
(stdin)= 30f678a157230290e00475cfffccbc92ae3659d94c145a2c0e9d0fa28f41c11a

有人可以帮我吗？

使用BitConverter类。

$secret = 'NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j'
$message = '/public/api/ver1/accounts/new?type=binance&name=binance_account&api_key=XXXXXX&secret=YYYYYY'

$hmacsha = New-Object System.Security.Cryptography.HMACSHA256
$hmacsha.key = [Text.Encoding]::ASCII.GetBytes($secret)
$signature1 = $hmacsha.ComputeHash([Text.Encoding]::ASCII.GetBytes($message))
#$signature2 = [Convert]::ToBase64String($signature1)

[System.BitConverter]::ToString($signature1) -replace '-', ''
