The AWS CloudHSM OpenSSL Provider supports the following key types with Client SDK 5.


****  

| Key Type | Description | 
| --- | --- | 
| RSA | RSA sign/verify and asymmetric encryption operations. Verification is offloaded to OpenSSL software. To generate RSA keys that are interoperable with the OpenSSL Provider, see [Export an asymmetric key with CloudHSM CLI](cloudhsm_cli-key-generate-file.md). | 
| EC | ECDSA sign/verify for P-256, P-384, and P-521 curves. Verification is offloaded to OpenSSL software. To generate EC keys that are interoperable with the OpenSSL Provider, see [Export an asymmetric key with CloudHSM CLI](cloudhsm_cli-key-generate-file.md). |
