    wolfSSL Supports Forward Secrecy

    • wolfssladmin
    Ever wondered what forward secrecy is and how it applies to SSL/TLS?  Forward secrecy protects current encryption even in the event of a future crack of a long term private key.  Using ephemeral keying in TLS with DHE or ECDHE yields this protection because the temporary key is unique and...

    Scaling with SSL

    • wolfssladmin
    Why is wolfSSL a great solution when you have millions of connections per server?  Memory consumption per connection can be as low as 3k, varying with the size of input and output buffers. This brings wolfSSL’s runtime memory consumption to 3-36kB depending on buffer size. Input and output buffers are...
