2024-04-09agent: Changes to the new KEM code in pkdecrypt.cWerner Koch1-22/+35
* agent/pkdecrypt.c (agent_hybrid_pgp_kem_decrypt): Replace fixed-info by an s-exp parameter. Do not expect the algo and extra length octet. -- This code needs more work, for example extracting the curve from the s-expression and mapping it to a KEM algo. It might even be better top move parts of the code to common/.

2024-02-25agent: Allow GET_PASSPHRASE in restricted mode.Werner Koch1-5/+4
* agent/command.c (cmd_get_passphrase): Allow use in restricted mode but ignore the cacheid. -- The use case is symmetric encryption via the extra-socket. To avoid that the gpg running on the server has access to the cache we set the cache id to NULL so that the cache is not used at all.
