Algorithm Support
This Crypto Token relies on support for different algorithms in Java and the SunPKCS11 provider/wrapper as well as support in the PKCS#11 standard, the used PKCS#11 driver from the HSM vendor, and the supported algorithms in the HSM. A complete list of supported algorithms can thus not be compiled here and the following lists algorithms that are tested and known to work with an HSM supporting it. Also, see the specific SignServer Signer for algorithms that signers can work with and review signer-specific algorithm support pages.

Key Algorithms
| Algorithm Name | Key Specification | Comment | |
|---|---|---|---|
| RSA | 1024 | Other key lengths are likely also working. |
| ECDSA | Named curves:
| More named curves are likely working. |
| ECDSA | Explicit Parameters | A signer can be configured using the EXPLICTECC parameter (see Other Properties) to encode the EC parameters explicitly in the request. This goes for the supported named curves but a named curve is still needed when generating the key-pair. But certificates with explicit EC parameters can no be read from the token.
Instead store the certificates in the worker configuration and certificates with explicit EC parameters can be used that way. |
| AES | 128 256 |
If the token contains certificates with explicit parameters the token can not be used by this crypto token until those certificates has been removed!
