Client SDK component comparison
In addition to the command-line tools, Client SDK 3 contains components that enable off-loading cryptographic operations to the HSM from various platform or language-based applications. Client SDK 5 does not have parity with Client SDK 3 at this time, but parity is the goal. The following table compares component availability in Client SDK 3 and Client SDK 5.
[1] CMU and KMU components are included in CloudHSM CLI with Client SDK 5.
