The way gcry_rsa and friends (the asymmetric ciphers) are loaded for the
pgp module is a bit quirky.
include/grub/crypto.h contains:
extern struct gcry_pk_spec *grub_crypto_pk_rsa;
commands/pgp.c contains the actual storage:
struct gcry_pk_spec *grub_crypto_pk_rsa;
And the module itself saves to the storage in pgp.c:
GRUB_MOD_INIT(gcry_rsa)
{
grub_crypto_pk_rsa = &_gcry_pubkey_spec_rsa;
}
This is annoying: gcry_rsa now has a dependency on pgp!
We want to be able to bring in gcry_rsa without bringing in PGP, so move the
storage to crypto.c.
Previously, gcry_rsa depended on pgp and mpi. Now it depends on crypto and mpi.
As pgp depends on crypto, this doesn't add any new module dependencies using
the PGP verfier.
[FWIW, the story is different for the symmetric ciphers. cryptodisk and friends
(zfs encryption etc) use grub_crypto_lookup_cipher_by_name() to get a cipher
handle. That depends on grub_ciphers being populated by people calling
grub_cipher_register. import_gcry.py ensures that the symmetric ciphers call it.]
