Quick ProTip: Negotiate TLS Connections In Powershell With A Minimum TLS Version Requirement
1. Проверить текущие настройки поддерживаемых протоколов
[Net.ServicePointManager]::SecurityProtocol
Возможные варианты
[enum]::GetNames([Net.SecurityProtocolType]) [System.Net.ServicePointManager]::SecurityProtocol = 'Tls11, Tls12'
В моей системе Windows 10 с Powershell v5.1 это значение возвращает значение SystemDefault. Это значение было введено в .NET 4.7 (предыдущие версии .NET не возвращают значения по умолчанию, только перечисляемый список) и позволяет вашей операционной системе выбирать протокол, с которым лучше всего согласовывать соединение. При обычных обстоятельствах это лучший вариант для использования, поскольку значения по умолчанию меняются в зависимости от текущей ситуации с безопасностью.
Однако SystemDefault может быть слишком мягким в объявлении доступных протоколов. SSLv3?! - Да, нет, спасибо.
Мы видим, что по умолчанию
Set strong cryptography on 64 bit .Net Framework (version 4 and above)
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
set strong cryptography on 32 bit .Net Framework (version 4 and above)
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
3. Перезапустить Powershell и проверить настройки поддерживаемых протоколов [Net.ServicePointManager]::SecurityProtocol
Open Powershell (As Admin)
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
