Product Description
CADP for C
CADP for C provides C/C++ based APIs for performing cryptographic and key management operations using CipherTrust Manager. It communicates with the CipherTrust Manager over NAE interfaces to manage the stored objects. It can also operate over KMIP.
CipherTrust Manager
With CipherTrust Manager, organizations can leverage a range of disparate software and hardware-based encryption products, while gaining the efficiency and security benefits of having all keys stored on a centralized, hardened security appliance.
The CipherTrust Manager offers robust capabilities for managing cryptographic keys across their lifecycle, including key generation, key import and export, key rotation, and much more. The CipherTrust Manager can be integrated through open APIs with virtually any off-the-shelf encryption product, including database encryption, laptop and device encryption, file and storage level encryption, and more.
Release Description
This release of CADP for C includes the new features and enhancements listed below.

Limitations
Wrapping and unwrapping are not supported for Asymmetric to Asymmetric keys.
Key Alias is not supported for Asymmetric keys.
Aliases are not supported for opaque objects.
NULL character is not supported in FPE/FF3 and FPE/FF3-1 algorithms.
Versioned Asymmetric keys are not supported.
DPM Headers are not supported for non-versioned keys and Muti-part operations.
RSA DPM header is supported in
LEGACY_VAE compatibilitymode only.Unwrapping of Opaque object with Symmetric key is not supported.
Wrapping and Unwrapping of Opaque object with Asymmetric key is not supported.
Associating an alias with a specific version of the key is not supported on the CipherTrust Manager. All the aliases get associated with the most active or latest version of the key.
