Compatible PKCS #11 Devices

This section has informative character. Knot DNS has been tested with several devices which claim to support PKCS #11 interface. The following table indicates which algorithms and operations have been observed to work. Please notice minimal GnuTLS library version required for particular algorithm support.

  Key generate Key import ECDSA 256-bit ECDSA 384-bit RSA 1024-bit RSA 2048-bit RSA 4096-bit DSA 512-bit DSA 1024-bit
Feitian ePass 2003 yes no no no yes yes no no no
SafeNet Network HSM (Luna SA 4) yes no no no yes yes yes no no
SoftHSM 2.0 yes yes yes yes yes yes yes yes yes
Trustway Proteccio NetHSM yes ECDSA only yes yes yes yes yes no no

The following table summarizes supported DNSSEC algorithm numbers and minimal GnuTLS library version required. Any algorithm may work with older library, however the supported operations may be limited (e.g. private key import).

  Numbers GnuTLS version
ECDSA 13, 14 3.4.8 or newer
RSA 5, 7, 8, 10 3.4.6 or newer
DSA 3, 6 3.4.10 or newer
