<a name="java-lib-keys_5"></a>

The AWS CloudHSM software library for Java enables you to generate the following key types.



| Key Type | Description | 
| --- | --- | 
| AES | Generate 128, 192, and 256-bit AES keys.  | 
| Triple DES (3DES, DESede) | Generate a 192-bit Triple DES Key [1](#java-lib-keys_5-note-1). | 
| EC | Generate EC key pairs – NIST curves secp224r1 (P-224), secp256r1 (P-256), secp256k1 (Blockchain), secp384r1 (P-384), secp521r1 (P-521), and ed25519[2](#java-lib-keys_5-note-2). | 
| GENERIC\_SECRET | Generate 1 to 800 bytes generic secrets. | 
| HMAC | Hash support for SHA1, SHA224, SHA256, SHA384, SHA512. | 
| ML-DSA | Generate ML-DSA[3](#java-lib-keys_5-note-3) key pairs with parameter sets ML-DSA-44, ML-DSA-65, and ML-DSA-87. | 
| RSA | Generate 2048-bit to 4096-bit RSA keys, in increments of 256 bits. | 

[1] In accordance with NIST guidance, this is disallowed for clusters in FIPS mode after 2023. For clusters in non-FIPS mode, it is still allowed after 2023. See [FIPS 140 Compliance: 2024 Mechanism Deprecation](compliance-dep-notif.md#compliance-dep-notif-1) for details.

[2] Only supported on hsm2m.medium instances in non-FIPS mode.

[3] Starting September 1, 2026, ML-DSA is available in FIPS mode for hsm2m.medium clusters.
