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
