Decrypted session ticket using encrypted ticket buffer.
Alignment not correct on platforms requiring 32-bit aligned access.
Copy the decrypted data into temporary for access.
Also zeroize the unencrypted tickets after use.
Digest size compared to key size - P521 has large key size.
Fixed to round down.
Added P-521 keys and certificates.
Added testing of P-521 keys and certificcates to unittest.
If `curLT` then diff needs to be decremented. For example: `diff` = 1 represents last packet so it would be the `window[idx] & (1 << 0)` bit of the window variable.
When handshake message is processed in wolfSSL_peek() then return
WANT_READ from peek instead of blocking waiting for application data.
Server may send an alert if the client certificate is invalid.
The server also may send NewSesionTicket after client has sent finished
message.
To detect alert before handling application data, then the socket needs
to be checked for data. If the data is an alert then wolfSSL_peek() will
handle the alert, but if it is a NewSessionTicket then wolfSSL_peek()
will process it and block waiting for application data - so return
WANT_READ if no application data seen after processing handshake
message.
Commit 6467de5 added some timing resistance to ECC shared secret
agreement. It involved adding an RNG object to the ecc keys so
a random z value can be added to the mix. The older FIPS release
has ECC outside the boundary, so it uses the new ECC code. FIPSv2
has ECC inside the boundary, but all the TLS code checks for that
version of FIPS and leaves out the calls to the new functions as
it is using an older version of ecc.c. FIPS Ready uses the latest
version of ecc.c but compiles as FIPSv2. So, the code outside of
the crypto layer is treating ECC as FIPSv2 and not calling the new
functions, but the crypto layer assumes the RNG should be present,
and errs out on testing.
1. Added a separate option for FIPS Ready to the enable-fips
configure option. `--enable-fips=ready`. It will treat FIPS
Ready as the next kind of FIPS release. FIPS Ready will be
treated like FIPS v3 in the build.
2. Changed the C preprocessor checks for FIPS version 2 to be
checks for not version 2, with respect to ECC Timing Resistance
and FIPS builds.
Added TLS 1.3 testing.
Added Ed25519 and Ed448 testing.
Added tesitng of OpenSSL client against wolfSSL server.
Fixed builds of Curve25519/Curve448/Ed25519/Ed448 in different
configurations.
An RNG is required for shared secret calculation now.
Use wc_ecc_set_rng() to set an RNG against the ECC object.
ECC verification does not need timing resistance and does not randomize
z ordinates.
