Andres Amaya Garcia 1f6301b3c8 Rename mbedtls_zeroize to mbedtls_platform_zeroize 2018-04-17 10:00:21 -05:00
Andres Amaya Garcia e32df087fb Remove individual copies of mbedtls_zeroize() 
This commit removes all the static occurrencies of the function
mbedtls_zeroize() in each of the individual .c modules. Instead the
function has been moved to utils.h that is included in each of the
modules.

Hanno Becker e2fcfa84ea Stick to the use of constant-macros 
This commit returns to using constant macros instead of global variables for the DHM group constants. Further, macros
providing the binary encoding of the primes from RFC 3526 and RFC 7919 are added. The hex-string macros are deprecated.

Janos Follath 1ad1c6d4e1 Fix typo 2017-09-21 12:05:30 +01:00
Janos Follath aa325d7b7f DHM: Fix dhm_check_range() always returning 0 
Although the variable ret was initialised to an error, the
MBEDTLS_MPI_CHK macro was overwriting it. Therefore it ended up being
0 whenewer the bignum computation was successfull and stayed 0
independently of the actual check.

* commit '95f0089':
  Update Changelog for DH params
  Add test case for dh params with privateValueLength
  accept PKCS#3 DH parameters with privateValueLength included

Conflicts:
	library/dhm.c
 2015-04-17 20:07:22 +02:00
Daniel Kahn Gillmor 2ed81733a6 accept PKCS#3 DH parameters with privateValueLength included 
library/dhm.c: accept (and ignore) optional privateValueLength for
PKCS#3 DH parameters.

PKCS#3 defines the ASN.1 encoding of a DH parameter set like this:

----------------
DHParameter ::= SEQUENCE {
  prime INTEGER, -- p
  base INTEGER, -- g
  privateValueLength INTEGER OPTIONAL }

The fields of type DHParameter have the following meanings:

     o    prime is the prime p.

     o    base is the base g.

     o    privateValueLength is the optional private-value
          length l.
----------------

See: ftp://ftp.rsasecurity.com/pub/pkcs/ascii/pkcs-3.asc

This optional parameter was added in PKCS#3 version 1.4, released
November 1, 1993.

dhm.c currently doesn't cope well with PKCS#3 files that have this
optional final parameter included. i see errors like:

------------
dhm_parse_dhmfile returned -0x33E6

Last error was: -0x33E6 - DHM - The ASN.1 data is not formatted correctly : ASN1 - Actual length differs from expected lengt
------------

You can generate PKCS#3 files with this final parameter with recent
versions of certtool from GnuTLS:

 certtool --generate-dh-params > dh.pem
