The JSON TTLV KMIP API
The easiest way to call the KMIP API is to use the ckms command line interface
or one of the Cosmian cloudproof libraries which provide wrapper calls
in the corresponding language.
Without the use of a library, the client must build the JSON TTLV messages from
an Operation
as described in the KMIP 2.1 specification, and issue an HTTP POST call to the /kmip/2_1 endpoint
of the server.
Multiple operations can be sent in a single call using the Messages API .
Easily building JSON TTLV messages
Building JSON TTLV messages is a complex task and the easiest way to get started is to use
the ckms CLI in JSON mode mode to print the corresponding request and response messages.
The JSON mode is activated by passing the --json flag to the ckms command.
See the JSON mode example below.
To send multiple requests in a single call, se the Messages API .
Sample JSON TTLV messages¶
Please refer to the various operations pages for sample JSON TTLV messages.
JSON mode example¶
This creates a (default AES 256) symmetric key which will be tagged with the string myKey.
The CLI will then show the JSON TTLV requests and response:
