PKCS#11 URL Generation#
(Nitrokey HSM 2 - Windows)
Various applications use openssl to handle e.g., TLS certificates. This concept mostly allows simply replacing a file-path (for the secret) with a so-called PKCS#11 URL to use a secret from a e.g., Nitrokey.
opensslcan use the PKCS#11 engine by installing
gnutls-binfor necessary tools
verify that your needed keys and/or certificates are available on your Nitrokey using
if you want to use ECC keys/mechanisms through
libengine-pkcs11-openssl, you’ll have to ensure its version is at least 0.4.10
List and Generate PKCS#11 URLs#
Use the following command to get a list of available tokens (Nitrokeys):
Choose the token (Nitrokey) URL you want to generate URL tokens for and use it like this:
p11tool --list-all <token-url> # example: # p11tool --list-all "pkcs11:model=PKCS%2315%20emulated;manufacturer=www.CardContact.de;serial=DENK0123123;token=UserPIN%20%28SmartCard-HSM%29"
If you inspect the tail of the URL you’ll recognize:
more, these can be partly removed as long as the necessary objects can be uniquely
identified using the resulting URL, see TLS Apache2 Configuration
for an example using
