    wolfSSL with ChaCha20-Poly1305 Cipher Suites

    • wolfssladmin
    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...

    When to use Pre Shared Key (PSK) Cipher Suites

    • wolfssladmin
    PSK cipher suites are a superb choice in low resource environments where both ends of the connection can be controlled. With PSK, each side of the connection has an already agreed upon key to use rather than agreeing on one during the TLS handshake. This reduces resource consumption for each...
