We have recently updated our ChaCha20-Poly1305 cipher suites. The ChaCha20-Poly1305 AEAD cipher suites are performant and use low amounts of memory, making it a good fit for IoT devices. This recent update allows for interoperability with the current OpenSSL, GnuTLS, and BoringSSL libraries when using ChaCha20-Poly1305 in a TLS connection and continues interoperability with libraries using the older version of RFCs like LibreSSL and the www.google.com server. For connection with the older RFC there has been an addition of ChaCha20-Poly1305 cipher suites ending with “-OLD” for example ECDHE-RSA-CHACHA20-POLY1305-OLD.
This most recent addition to the wolfSSL embedded SSL/TLS library is on our GitHub account located at https://github.com/wolfSSL/wolfssl and will be coming to the wolfSSL website https://wolfssl.com/download in our next release, scheduled for the end of February.
