I am trying to understand the differences in key types and looking at encryption keys in particular. RFC 4880 has this to say on the matter of key flags:
0x04 - This key may be used to encrypt communications.
0x08 - This key may be used to encrypt storage.
So, my first question is why is there a distinction between the two
types of encryption?
Also, looking in GnuPG 1.4.9, I see this in g10/keygen.c:
if (use & PUBKEY_USAGE_ENC)
buf[0] |= 0x04 | 0x08;
Which suggests, quite strongly, that the distinction is irrelevant. Why
GnuPG ignore the different encryption key types?
Thank you, James
