Hanno Becker d4a872ee67 Rename internal MBEDTLS_ENTROPY_HAVE_STRONG to ENTROPY_HAVE_STRONG
This commit renames the test-only flag MBEDTLS_ENTROPY_HAVE_STRONG to ENTROPY_HAVE_STRONG to make it more transparent
that it's an internal flag, and also to content the testscript tests/scripts/check-names.pl which previously complained
about the macro occurring in a comment in `entropy.c` without being defined in a library file.

Hanno Becker d7f3520360 Don't add extensions for X.509 non-v3 certificates
This commit removes extension-writing code for X.509 non-v3 certificates from
mbedtls_x509write_crt_der. Previously, even if no extensions were present an
empty sequence would have been added.

Hanno Becker 6c13d37961 Extend cert_write example program by multiple cmd line options
This commit adds the following command line options to programs/x509/cert_write:

- authority_identifier (val 0, 1): Enable or disable the addition of the
                                   authority identifier extension.
- subject_identifier (val 0, 1): Enable or disable the addition of the
                                 subject identifier extension.
- basic_constraints (val 0, 1): Enable or disable the addition of the
                                basic constraints extension.
- md (val MD5, SHA1, SHA256, SHA512): Set the hash function used
                                      when creating the CRT.

Hanno Becker 5a4f172522 Add suffix for 1024-bit RSA key files
Previously, 2048-bit and 4096-bit RSA key files had their bitsize indicated in their filename, while the original
1024-bit keys hadn't. This commit unifies the naming scheme by always indicating the bitsize in the filename.

Hanno Becker 55b1a0af0c Add further tests for DER-encoded PKCS8-v2-DES encrypted RSA keys

PKCS8-v2-3DES encrypted RSA keys.

Hanno Becker 7d108257a4 Add further tests for new RSA keys

Hanno Becker d16f6126c7 Add RSA key generation commands to test Makefile
This commit adds the commands used to generate the various RSA keys to tests/Makefile so that they can be easily
regenerated or modified, e.g. if larger key sizes or other encryption algorithms need to be tested in the future.

Hanno Becker fab3569963 Use in-place decryption in pk_parse_pkcs8_encrypted_der
The stack buffer used to hold the decrypted key in pk_parse_pkcs8_encrypted_der
was statically sized to 2048 bytes, which is not enough for DER encoded 4096bit
RSA keys.

This commit resolves the problem by performing the key-decryption in-place,
circumventing the introduction of another stack or heap copy of the key.

There are two situations where pk_parse_pkcs8_encrypted_der is invoked:
1. When processing a PEM-encoded encrypted key in mbedtls_pk_parse_key.
   This does not need adaption since the PEM context used to hold the decoded
   key is already constructed and owned by mbedtls_pk_parse_key.
2. When processing a DER-encoded encrypted key in mbedtls_pk_parse_key.
   In this case, mbedtls_pk_parse_key calls pk_parse_pkcs8_encrypted_der with
   the buffer provided by the user, which is declared const. The commit
   therefore adds a small code paths making a copy of the keybuffer before
   calling pk_parse_pkcs8_encrypted_der.

Andres Amaya Garcia 7c02c503ea Change PK module preprocessor check on word size
There were preprocessor directives in pk.c and pk_wrap.c that cheked
whether the bit length of size_t was greater than that of unsigned int.
However, the check relied on the MBEDTLS_HAVE_INT64 macro being defined
which is not directly related to size_t. This might result in errors in
some platforms. This change modifies the check to use the macros
SIZE_MAX and UINT_MAX instead making the code more robust.

Hanno Becker 61937d4a83 Rename time and index parameter to avoid name conflict.
As noted in #557, several functions use 'index' resp. 'time'
as parameter names in their declaration and/or definition, causing name
conflicts with the functions in the C standard library of the same
name some compilers warn about.

This commit renames the arguments accordingly.

Hanno Becker ce37e6269e Reliably zeroize sensitive data in AES sample application
The AES sample application programs/aes/aescrypt2 could miss zeroizing
the stack-based key buffer in case of an error during operation. This
commit fixes this and also clears another temporary buffer as well as
all command line arguments (one of which might be the key) before exit.
