If the old length checking method is desired `NO_STRICT_ECDSA_LEN` can be used. This would allow extra signature byes at the end (unused and not altering verification result). This is kept for possible backwards compatibility.
Per RFC6979: `How a signature is to be encoded is not covered by the DSA and ECDSA standards themselves; a common way is to use a DER-encoded ASN.1 structure (a SEQUENCE of two INTEGERs, for r and s, in that order).`
ANSI X9.62: ASN.1 Encoding of ECDSA:
```
ECDSA-Sig-Value ::= SEQUENCE {
r INTEGER,
s INTEGER
}
```
Fixes#2088
OCSP uses an identified hash of the issuer's public key to identify the
certificate's signer. (Typically this is SHA-1, but can be any SHA
hash.) The AKID/SKID for the certificates usually are the SHA-1 hash of
the public key, but may be anything. We cannot depend on the AKID for
OCSP purposes. For OCSP lookups, wolfSSL calculates the hash of the
public key based on the copy saved for use with the handshake signing.
For RSA, that was fine. For ECDSA, we use the whole public key including
the curve ID, but for OCSP the curve ID isn't hashed. Stored the hash of
the public key at the point where we are looking at the key when reading
in the certificate, and saving the hash in the signer record.
Getting the seed from a device has been added.
If the HASH_DRBG is available, PKCS#11 will be used for generating the
seed.
Otherwise, all generated random data will come from PKCS#11 device.
hardware acceleration with RSA
add AES-GCM hardware acceleration
refactor setting RSA IV flag
check and set AF_ALG flags
fix for default AF_ALG use
set buffer alignment with Xilinx RSA
macro guard after rebase
use ALIGN64
clean up test cases
- Added support for Deos with no file system
- Implemented a custom malloc since reusing and freeing memory is disallowed in avionics and mission critical applications.
- Added TLS client and server example with a TCP setup mailbox transport
- Timer starts at an offset of CURRENT_UNIX_TIMESTAMP specified by the user
- Uses rand_r() as a pseudo random number generator and uses the current time in seconds as a seed
- Uses strnicmp for XSTRNCASECMP instead of strncasecmp
- a readme doc included
