Things ideal for 1.05 For 1.06
- ASN.1 SET and UTCtime and CHOICE (hint for choice do it as a sep list and just use error codes to know when you got a hit)
- Start working towards making the bignum code plugable
- Add OID for ciphers and PRNGs to their descriptors
- Document the ASN.1 a bit more verbosely ;-)
- Some ASN.1 demo programs [for now read the source code!]
- export ECC functions globally
- Look into other ECC point muls and consider a "precomp" interface
1. export ECC functions globally [e.g. mulmod and the sets]
- goal is tv_gen module and test vectors
2. ASN.1 SET and T61String
3. phase out DH code [RSA/ECC/DSA is enough]
4. Some ASN.1 demo programs [for now read the source code!]
5. Start working towards making the bignum code plugable
6. Look into other ECC point muls and consider a "precomp" interface
7. Add OID for ciphers and PRNGs to their descriptors

v1.05
-- Added Technote #6 which covers the current PK compliance.
-- Fixed buffer overflow in OAEP decoder
-- Added CHOICE to the list of ASN.1 types
-- Added UTCTIME to the list of ASN.1 types
-- Added MUTEX locks around descriptor table functions [but not on the functions that are dependent on them]
All functions call *_is_valid() before using a descriptor index which means the respective table must be unlocked before
it can be accessed. However, during the operation [e.g. CCM] if the descriptor has been altered the results will be
undefined.
-- Minor updates to the manual to reflect recent changes
-- Added a catch to for an error that should never come up in rsa_exptmod(). Just being thorough.

\subsection{ASN.1 UTCTIME}
The UTCTIME type is to store a date and time in ASN.1 format. It uses the following structure to organize the time.
\begin{verbatim}
typedef struct {
unsigned YY, /* year 00--99 */
MM, /* month 01--12 */
DD, /* day 01--31 */
hh, /* hour 00--23 */
mm, /* minute 00--59 */
ss, /* second 00--59 */
off_dir, /* timezone offset direction 0 == +, 1 == - */
off_hh, /* timezone offset hours */
off_mm; /* timezone offset minutes */
} ltc_utctime;
\end{verbatim}
The time can be offset plus or minus a set amount of hours (off\_hh) and minutes (off\_mm). When ``off\_dir'' is zero the time will be added otherwise it
will be subtracted.
For instance, the array $\lbrace 5, 6, 20, 22, 4, 00, 0, 5, 0 \rbrace$ represents the current time of 2005, June 20th, 22:04:00 with a time offset of +05h00.
\index{der\_encode\_utctime()}
\index{der\_decode\_utctime()}
\index{der\_length\_utctime()}
\begin{verbatim}
int der_encode_utctime(ltc_utctime *utctime,
unsigned char *out, unsigned long *outlen);
int der_decode_utctime(const unsigned char *in, unsigned long *inlen,
ltc_utctime *out);
int der_length_utctime(ltc_utctime *utctime, unsigned long *outlen);
\end{verbatim}
The encoder will store time in one of the two ASN.1 formats, either ``YYMMDDhhmmssZ'' or ``YYMMDDhhmmss$\pm$hhmm'' and perform minimal error checking on the
input. The decoder will read all valid ASN.1 formats and perform range checking on the values (not complete but rational) useful for catching packet errors.
It is suggested that decoded data be further scrutinized (e.g. days of month in particular).
\subsection{ASN.1 CHOICE}
The CHOICE ASN.1 type represents a union of ASN.1 types all of which are stored in a ``ltc\_asn1\_list''. There is no encoder for the CHOICE type, only a
decoder. The decoder will scan through the provided list attempting to use the appropriate decoder on the input packet. The list can contain any ASN.1 data
type\footnote{Except it cannot have LTC\_ASN1\_INTEGER and LTC\_ASN1\_SHORT\_INTEGER simultaneously.} except for other CHOICE types.
There is no encoder for the CHOICE type as the actual DER encoding is the encoding of the chosen type.
\index{der\_decode\_choice()}
\begin{verbatim}
int der_decode_choice(const unsigned char *in, unsigned long *inlen,
ltc_asn1_list *list, unsigned long outlen);
\end{verbatim}
This will decode the input in the ``in'' field of length ``inlen''. It uses the provided ASN.1 list specified in the ``list'' field which has ``outlen'' elements.
The ``inlen'' field will be updated with the length of the decoded data type as well as the respective entry in the ``list'' field will have the ``used'' flag
set to non--zero to reflect it was the data type decoded.

Tech Note 0006
PK Standards Compliance
Tom St Denis
RSA
----
PKCS #1 compliance.
Key Format: RSAPublicKey and RSAPrivateKey as per PKCS #1 v2.1
Encryption: OAEP as per PKCS #1
Signature : PSS as per PKCS #1
DSA
----
The NIST DSA algorithm
Key Format: HomeBrew [see below]
Signature : ANSI X9.62 format [see below].
Keys are stored as
DSAPublicKey ::= SEQUENCE {
publicFlags BIT STRING(1), -- must be 0
g INTEGER , -- base generator, check that g^q mod p == 1
-- and that 1 < g < p - 1
p INTEGER , -- prime modulus
q INTEGER , -- order of sub-group (must be prime)
y INTEGER , -- public key, specifically, g^x mod p,
-- check that y^q mod p == 1
-- and that 1 < y < p - 1
}
DSAPrivateKey ::= SEQUENCE {
publicFlags BIT STRING(1), -- must be 1
g INTEGER , -- base generator, check that g^q mod p == 1
-- and that 1 < g < p - 1
p INTEGER , -- prime modulus
q INTEGER , -- order of sub-group (must be prime)
y INTEGER , -- public key, specifically, g^x mod p,
-- check that y^q mod p == 1
-- and that 1 < y < p - 1
x INTEGER -- private key
}
Signatures are stored as
DSASignature ::= SEQUENCE {
r, s INTEGER -- signature parameters
}
ECC
----
The ANSI X9.62 and X9.63 algorithms [partial]. Supports all NIST GF(p) curves.
Key Format : Homebrew [see below, only GF(p) NIST curves supported]
Signature : X9.62 compliant
Encryption : Homebrew [based on X9.63, differs in that the public point is stored as an ECCPublicKey]
Shared Secret: X9.63 compliant
ECCPublicKey ::= SEQUENCE {
flags BIT STRING(1), -- public/private flag (always zero),
keySize INTEGER, -- Curve size (in bits) divided by eight
-- and rounded down, e.g. 521 => 65
pubkey.x INTEGER, -- The X co-ordinate of the public key point
pubkey.y INTEGER, -- The Y co-ordinate of the public key point
}
ECCPrivateKey ::= SEQUENCE {
flags BIT STRING(1), -- public/private flag (always one),
keySize INTEGER, -- Curve size (in bits) divided by eight
-- and rounded down, e.g. 521 => 65
pubkey.x INTEGER, -- The X co-ordinate of the public key point
pubkey.y INTEGER, -- The Y co-ordinate of the public key point
secret.k INTEGER, -- The secret key scalar
}
The encryption works by finding the X9.63 shared secret and hashing it. The hash is then simply XOR'ed against the message [which must be at most the size
of the hash digest]. The format of the encrypted text is as follows
ECCEncrypted ::= SEQUENCE {
hashOID OBJECT IDENTIFIER, -- The OID of the hash used
pubkey OCTET STRING , -- Encapsulation of a random ECCPublicKey
skey OCTET STRING -- The encrypted text (which the hash was XOR'ed against)
}
