Hi, file knows about the keybox format: GPG keybox database version 1, created-at [...] Here is the format description: The first blob of a plain KBX file has a special format: - u32 Length of this blob - byte Blob type (1) - byte Version number (1) - u16 Header flags bit 0 - RFU bit 1 - Is being or has been used for OpenPGP blobs - b4 Magic 'KBXf' - u32 RFU - u32 file_created_at - u32 last_maintenance_run - u32 RFU - u32 RFU gpg uses this code to detect keybox files: --8<---------------cut here---------------start------------->8--- u32 magic; unsigned char verbuf[4]; FILE *fp; fp = fopen (filename, "rb"); if (fp) { *r_found = 1; if (fread (&magic, 4, 1, fp) == 1 ) { if (magic == 0x13579ace || magic == 0xce9a5713) ; /* GDBM magic - not anymore supported. */ else if (fread (&verbuf, 4, 1, fp) == 1 && verbuf[0] == 1 && fread (&magic, 4, 1, fp) == 1 && !memcmp (&magic, "KBXf", 4)) { if ((verbuf[3] & 0x02)) *r_openpgp = 1; rt = KEYDB_RESOURCE_TYPE_KEYBOX; } else rt = KEYDB_RESOURCE_TYPE_KEYRING; } else /* Maybe empty: assume keyring. */ rt = KEYDB_RESOURCE_TYPE_KEYRING; fclose (fp); } --8<---------------cut here---------------end--------------->8--- Shalom-Salam, Werner -- Die Gedanken sind frei.
