New macro MBEDTLS_PK_OPAQUE_INFO_1 to initialize mbedtls_pk_info_t structures.
Document that this macro must be used in engine implementations for forward
compatibility. Use this macro rather than accessing the structure directly
in tests and in the sample engine to set a good example.
New functions to write a representation of an elliptic curve group and
point according to X9.62 and RFC5480: ECParameters as OID and ECPoint
as octet string.
Change the documentation of mbedtls_pk_rsa and mbedtls_pk_ec to
require that mbedtls_pk_get_type returns a corresponding transparent
key time.
Change the implementation of mbedtls_pk_rsa and mbedtls_pk_ec to
return NULL if called with an argument that is not suitable, rather
than returning an invalid pointer.
Add a new key pair object type: MBEDTLS_PK_OPAQUE, intended for
implementations of asymmetric cryptography operations that call an
external cryptographic module.
External cryptographic module engines must implement the API described
by a mbedtls_pk_info_t structure and, usually, a custom setup function.
Document the fields of the mbedtls_pk_info_t structure and the
requirements on a PK engine. Also document non-obvious aspects of the
behavior of the pk interface functions on opaque keys.
Change the interface of check_pair_func to take a pointer to a full
mbedtls_pk_context as its pub argument, and not just the data part of
the context. This is necessary because when prv is opaque, pub may
legitimately be of a different type (typically prv would be opaque and
pub would be transparent).
This is in preparation to adding support for opaque keys in the pk layer. The
header files are for use as follows:
* pk.h for users of the pk interface.
* pk_info.h for implementers of opaque key engines.
* pk_internal.h only inside libmbedcrypto to implement built-in pk types.
Expose a function mbedtls_pk_signature_size to calculate the maximum
size of a signature made with a given key. Document that this is the
buffer size that mbedtls_pk_sign requires.
Add a corresponding field signature_size_func to the mbedtls_pk_info
structure.
Expose ecdsa_signature_to_asn1 in the API. It's useful when converting
between RFC 4492 format and other representations that might be used
in external crypto processors.
Expose a macro MBEDTLS_ECDSA_MAX_SIG_LEN and a function
mbedtls_ecdsa_max_sig_len to calculate the size of an ECDSA signature
based on the curve size.
Document that this is the buffer size that
mbedtls_ecdsa_write_signature requires.
In the mbedtls_pk_info_t method can_do, pass the context data. This
will be needed for opaque keys, where the info structure depends on
the method to access the opaque key and not on the key type.
- Adapt the change in all.sh to the new keep-going mode
- Restore alphabetical order of configuration flags for
alternative implementations in config.h and rebuild
library/version_features.c
Conflict resolution: additions in the same places as
upstream-public/pr/865, both adding into lexicographically sorted
lists, resolved by taking the additions in lexicographic order.
* public/pr/1136:
Timing self test: shorten redundant tests
Timing self test: increased duration
Timing self test: increased tolerance
Timing unit tests: more protection against infinite loops
Unit test for mbedtls_timing_hardclock
New timing unit tests
selftest: allow excluding a subset of the tests
selftest: allow running a subset of the tests
selftest: refactor to separate the list of tests from the logic
Timing self test: print some diagnosis information
mbedtls_timing_get_timer: don't use uninitialized memory
timing interface documentation: minor clarifications
Timing: fix mbedtls_set_alarm(0) on Unix/POSIX
* Correct order of sections in ChangeLog
* Restore unintentionally removed whitespace and
formatting improvements.
* Consistently rename MBEDTLS_ERR_RSA_EXPORT_UNSUPPORTED
to MBEDTLS_ERR_RSA_UNSUPPORTED_OPERATION in rsa.h
documentation.
mbedtls_timing_get_timer with reset=1 is called both to initialize a
timer object and to reset an already-initialized object. In an
initial call, the content of the data structure is indeterminate, so
the code should not read from it. This could crash if signed overflows
trap, for example.
As a consequence, on reset, we can't return the previously elapsed
time as was previously done on Windows. Return 0 as was done on Unix.
* restricted/pr/397:
Don't split error code description across multiple lines
Register new error code in error.h
Move deprecation to separate section in ChangeLog
Extend scope of ERR_RSA_UNSUPPORTED_OPERATION error code
Adapt RSA test suite
Adapt ChangeLog
Deprecate usage of RSA primitives with wrong key type
This commit splits off the RSA helper functions into separate headers and
compilation units to have a clearer separation of the public RSA interface,
intended to be used by end-users, and the helper functions which are publicly
provided only for the benefit of designers of alternative RSA implementations.
1) move the change into Features from Changes, in the changLog
2) Change the feature alternative configuration MBEDTLS_ECDH_ALT
definition to function alternative defintions
MBEDTLS_ECDH_COMPUTE_SHARED_ALT and MBEDTLS_ECDH_GEN_PUBLIC_ALT
1) update ChangLog to have new feature in Features instead of Changes
2) Change MBEDTLS_ECDSA_ALT to function specific alternative definitions:
MBEDTLS_ECDSA_SIGN_ALT, MBEDTLS_ECDSA_VERIFY_ALT and MBEDTLS_ECDSA_GENKEY_ALT
