* gpg: New option --override-compliance-checkWerner Koch2021-10-133-12/+47
| | | | | | | | | | | | | | | | | | | | | | | * g10/gpg.c (oOverrideComplianceCheck): New. (opts): Add new option. (main): Set option and add check for batch mode. * g10/options.h (opt): Add flags.override_compliance_check. * g10/sig-check.c (check_signature2): Factor complaince checking out to ... (check_key_verify_compliance): this. Turn error into a warning in override mode. -- There is one important use case for this: For systems configured globally to use de-vs mode, Ed25519 and other key types are not allowed because they are not listred in the BSI algorithm catalog. Now, our release signing keys happen to be Ed25519 and thus we need to offer a way for users to check new versions even if the system is in de-vs mode. This does on purpose not work in --batch mode so that scripted solutions won't accidently pass a signature check. GnuPG-bug-id: 5655

Due to the mode the pattern send to dirmngr was prefixed with a '=' and thus dirmngr used an exact search;.

We will eventually remove this option becuase it was marked as an experimental feature anyway. It would be too confusing if gpg and gpgsm use different key storages. Further, other components (e.g. dirmngr or gpg-wks-client) which call gpg or gpgsm need to be aware that the keyboxd is used and pass that option on the command line. Now that common.conf is always read (even if --no-options is used) those tools will work instantly.

This works only with an LDAP directory because it can be expected that the public key has been put into the LDAP during card personalization. Of course an LDAP server needs to be configured; in a Windows AD domain this can be a mere "keyserver ldap:///" in dirmngr.conf. Other configured keyservers are ignored. Requirements for the card driver: The $SIGNKEYID attribute must exists and a query for the KEY-FPR attribute needs to return the OpenPGP fingerprint for that key. This is currently supported for OpenPGP cards and certain PKCS#15 cards. Signed-off-by: Werner Koch <[email protected]>

(agent/command.c): Register new command KEYTOTPM. * g10/call-agent.c (agent_keytotpm): New. * g10/keyedit.c (cmdKEYTOTPM): New command "keytotpm". (keyedit_menu): Implement. -- The plumbing is done in two parts: the agent is modified to understand a KEYTOTPM assuan command taking the key grip as an argument. This simply obtains the key s expression and calls the existing writeky diversion to the tpm2daemon. The daemon reponds with the TPM conversion of the key and that key is then stored in the keyfile as a shadowed-private-key with "tpm2-v1" type. To effect the conversion, all the user does from gpg --edit-key is select which private key they wish to move (or move the primary if no key is selected) and type keytotpm. The conversion to TPM form is instantaneous and once converted, the actual key cannot be recovered, meaning that if you want your gpg key to move to a new laptop you must keep an unconverted backup copy in a safe location. When you do a list command, all TPM keys show up as card-no: TPM-Protected The key is stored encrypted to the TPM2 storage seed and since each TPM has a unique seed, only the single TPM contained in your laptop can now read the key. This means you cannot simply copy the shadowed key file over to a new laptop, you must copy over the backup copy and then convert it to TPM form on the new laptop. To decomission your laptop, execute a tssclear command which regenerates the storage seed and effectively shreds all keys. Note when you have done this *every* TPM2 shadowed private key becomes unreadable by any TPM and all are effectively destroyed.
