Persistent Passphrase Format
============================
To allow persistent storage of cached passphrases we use a scheme
similar to the private-key storage format. This is a master
passphrase format where each file may protect several secrets under
one master passphrase. It is possible to have several of those files
each protected by a dedicated master passphrase. Clear text keywords
allow to list the available protected passphrases.
The name of the files with these protected secrets have this form:
pw-<string>.dat. STRING may be an arbitrary string, as a default name
for the passphrase storage the name "pw-default.dat" is suggested.
(protected-shared-secret
((desc descriptive_text)
(key [key_1] (keyword_1 keyword_2 keyword_n))
(key [key_2] (keyword_21 keyword_22 keyword_2n))
(key [key_n] (keyword_n1 keyword_n2 keyword_nn))
(protected mode (parms) encrypted_octet_string)
(protected-at <isotimestamp>)
)
)
After decryption the encrypted_octet_string yields this S-expression:
(
(
(value key_1 value_1)
(value key_2 value_2)
(value key_n value_n)
)
(hash sha1 #...[hashvalue]...#)
)
The "descriptive_text" is displayed with the prompt to enter the
unprotection passphrase.
KEY_1 to KEY_N are unique identifiers for the shared secret, for
example an URI. In case this information should be kept confidential
as well, they may not appear in the unprotected part; however they are
mandatory in the encrypted_octet_string. The list of keywords is
optional. The oder of the "key" lists and the order of the "value"
lists mut match, that is the first "key"-list is associated with the
first "value" list in the encrypted_octet_string.
The protection mode etc. is indentical to the protection mode as
decribed for the private key format.
list of the secret key parameters. The protected-at expression is
optional; the isotimestamp is 15 bytes long (e.g. "19610711T172000").
The "hash" in the encrypted_octet_string is calculated on the
concatenation of the key list and value lists: i.e it is required to
hash the concatenation of all these lists, including the
parenthesis and (if used) the protected-at list.
Example:
(protected-shared-secret
((desc "List of system passphrases")
(key "uid-1002" ("Knuth" "Donald Ervin Knuth"))
(key "uid-1001" ("Dijkstra" "Edsgar Wybe Dijkstra"))
(key)
(protected mode (parms) encrypted_octet_string)
(protected-at "20100915T111722")
)
)
with "encrypted_octet_string" decoding to:
(
(
(value 4:1002 "signal flags at the lock")
(value 4:1001 "taocp")
(value 1:0 "premature optimization is the root of all evil")
)
(hash sha1 #0102030405060708091011121314151617181920#)
)
To compute the hash this S-expression (in canoncical format) was
hashed:
((desc "List of system passphrases")
(key "uid-1002" ("Knuth" "Donald Ervin Knuth"))
(key "uid-1001" ("Dijkstra" "Edsgar Wybe Dijkstra"))
(key)
(value 4:1002 "signal flags at the lock")
(value 4:1001 "taocp")
(value 1:0 "premature optimization is the root of all evil")
