Key attributes in the PKCS #11 library for AWS CloudHSM Client SDK 5

An AWS CloudHSM key object can be a public, private, or secret key. Actions permitted on a key object are specified through attributes. Attributes are defined when the key object is created. When you use the PKCS #11 library for AWS CloudHSM, we assign default values as specified by the PKCS #11 standard.

AWS CloudHSM does not support all attributes listed in the PKCS #11 specification. We are compliant with the specification for all attributes we support. These attributes are listed in the respective tables.

Cryptographic functions such as C_CreateObject, C_GenerateKey, C_GenerateKeyPair, C_UnwrapKey, and C_DeriveKey that create, modify, or copy objects take an attribute template as one of their parameters. For more information about passing an attribute template during object creation, see Generate keys through PKCS #11 library for examples.
