2.5. 生成对称密钥
要生成对称密钥，请使用 order create 命令，然后将密钥存储在 barbican 中。然后，您可以将对称密钥用于某些任务，如 nova 磁盘加密和 swift 对象加密。
前提条件
- OpenStack Key Manager 已安装并运行
流程
使用
顺序创建并将其保存在 barbican 中，生成 256 位密钥。例如：$ openstack secret order create --name swift_key --algorithm aes --mode ctr --bit-length 256 --payload-content-type=application/octet-stream key +----------------+-----------------------------------------------------------------------------------+ | Field | Value | +----------------+-----------------------------------------------------------------------------------+ | Order href | https://192.168.123.173:9311/v1/orders/043383fe-d504-42cf-a9b1-bc328d0b4832 | | Type | Key | | Container href | N/A | | Secret href | None | | Created | None | | Status | None | | Error code | None | | Error message | None | +----------------+-----------------------------------------------------------------------------------+
您还可以使用
--mode选项将生成的密钥配置为使用特定模式，如ctr或cbc。如需更多信息，请参阅 NIST SP 800-38A。查看识别所生成密钥位置的顺序详情，如
Secret href值所示：$ openstack secret order get https://192.168.123.173:9311/v1/orders/043383fe-d504-42cf-a9b1-bc328d0b4832 +----------------+------------------------------------------------------------------------------------+ | Field | Value | +----------------+------------------------------------------------------------------------------------+ | Order href | https://192.168.123.173:9311/v1/orders/043383fe-d504-42cf-a9b1-bc328d0b4832 | | Type | Key | | Container href | N/A | | Secret href | https://192.168.123.173:9311/v1/secrets/efcfec49-b9a3-4425-a9b6-5ba69cb18719 | | Created | 2018-01-24T04:24:33+00:00 | | Status | ACTIVE | | Error code | None | | Error message | None | +----------------+------------------------------------------------------------------------------------+
