28144decef PKCS#5 v2 PBES2 support and use in PKCS#8 encrypted certificates
The error code POLARSSL_ERR_X509_PASSWORD_MISMATCH is now properly
returned in case of an encryption failure in the padding. The
POLARSSL_ERR_X509_PASSWORD_REQUIRED error code is only returned for PEM
formatted private keys as for DER formatted ones it is impossible to
distinguish if a DER blob is PKCS#8 encrypted or not.

2a84424a35 Disabled the HAVEGE random generator by default
Rationale: The HAVEGE random generator has too many caveats to be a
standard generator that people rely on. The HAVEGE random generator is not
suitable for virtualized environments. In addition the HAVEGE random
generator is dependent on timing and specific processor traits that
cannot be guaranteed by default on compile time.

Our advice: only use HAVEGE as an additional random source for your
entropy pool, never as your primary source.

d5c2b542cc Indication of x509_get_numeric_string() deprecation 2013-04-07 22:34:26 +02:00
Paul Bakker
c70b982056 OID functionality moved to a separate module.
A new OID module has been created that contains the main OID searching
functionality based on type-dependent arrays. A base type is used to
contain the basic values (oid_descriptor_t) and that type is extended to
contain type specific information (like a pk_alg_t).

As a result the rsa sign and verify function prototypes have changed. They
now expect a md_type_t identifier instead of the removed RSA_SIG_XXX
defines.

All OID definitions have been moved to oid.h
All OID matching code is in the OID module.

The RSA PKCS#1 functions cleaned up as a result and adapted to use the
MD layer.

The SSL layer cleanup up as a result and adapted to use the MD layer.

The X509 parser cleaned up and matches OIDs in certificates with new
module and adapted to use the MD layer.

The X509 writer cleaned up and adapted to use the MD layer.
