ESP8266_NONOS_SDK  3.0

The axTLS library has features such as:

  • The TLSv1 SSL client/server protocol
  • No requirement to use any openssl libraries.
  • A choice between AES block (128/256 bit) and RC4 (128 bit) stream ciphers.
  • RSA encryption/decryption with variable sized keys (up to 4096 bits).
  • Certificate chaining and peer authentication.
  • Session resumption, session renegotiation.
  • ASN.1, X.509, PKCS#8, PKCS#12 keys/certificates with DER/PEM encoding.
  • Highly configurable compile time options.
  • Portable across many platforms (written in ANSI C), and has language bindings in C, C#, VB.NET, Java, Perl and Lua.
  • Partial openssl API compatibility (via a wrapper).
  • A very small footprint (around 50-60kB for the library in 'server-only' mode).
  • No dependencies on sockets - can use serial connections for example.
  • A very simple API - ~ 20 functions/methods.

A list of these functions/methods are described below.
