Fix to calc BuildSHA_CertVerify if WOLFSSL_ALLOW_TLS_SHA1. Fix to add check for DTLS to not allow stream ciphers. Removed the RC4 tests from the test-dtls.conf. Added support for using default suites on client side. Switched the arg to “-H”. Cleanup of the example server/client args list. Fixes for build with “--disable-sha”.
