dnssec-keyfromlabel not working with Debian 12 (bookworm)

[Gérard Parat]

Hi,

Weird behavior with /opt/bind9/etc/openssl.cnf.

The only difference with /etc/ssl/openssl.cnf is the pkcs11 engine:

[openssl_init]

engines=engine_section

[engine_section]

pkcs11 = pkcs11_section

[pkcs11_section]

engine_id = pkcs11

dynamic_path = /usr/lib/x86_64-linux-gnu/engines-3/pkcs11.so

MODULE_PATH = /usr/lib/softhsm/libsofthsm2.so

init = 0

For example, dig is not working with environment variable OPENSSL_CONF:

$ dig www.internet.nl +short
04-Dec-2023 00:39:24.280 EVP_PKEY_fromdata_init failed (crypto failure)
04-Dec-2023 00:39:24.280 error:03000096:digital envelope 
routines::operation not supported for this 
keytype:../crypto/evp/pmeth_gn.c:354:
dig: dst_lib_init: crypto failure

It works if OPENSSL_CONF is undefined:

$ OPENSSL_CONF= dig www.internet.nl +short
proloprod.internet.nl.
62.204.66.10

Issue seems wider than only relative to dnssec-keyfromlabel.
