Dear Alibaba Cloud users,
To provide enhanced services, Alibaba Cloud Key Management Service (KMS) will update the supported Transport Layer Security (TLS) versions for KMS instances in the US (Virginia) and US (Silicon Valley) regions.
Effective time
Aug. 7, 2025 (UTC+8)
Before the update
KMS instances support TLS 1.0, TLS 1.1, and TLS 1.2, regardless of whether they are accessed via a dedicated or shared gateway.
After the update
Newly purchased KMS instances support TLS 1.2 only, with an exception for those purchased by existing users accessed via the shared gateway.
User type | Supported TLS (dedicated gateway) | Supported TLS (shared gateway) |
New users | TLS 1.2 | TLS 1.2 |
Existing users | TLS 1.2 | TLS 1.0, TLS 1.1, and TLS 1.2 |
For existing instances, the supported TLS versions remain unchanged (TLS 1.0, TLS 1.1, and TLS 1.2).
To enable or disable TLS 1.0 or TLS 1.1, contact us.
Thank you for your understanding and support.
