Crate wolfssl

The wolfssl crate is designed to be a Rust layer built on top of the wolfssl-sys crate (a C passthrough crate).

Structs

• Chacha20Poly1305Aead
  Struct for encrypt/decrypt using Chacha20 cipher and authentication using Poly1305
• Context
  A wrapper around a WOLFSSL_CTX.
• ContextBuilder
  Produces a Context once built.
• Random
  Provides a way to extract random values from WolfSSL.
• Session
  Wraps a WOLFSSL pointer, as well as the additional fields needed to write into, and read from, wolfSSL’s custom IO callbacks.
• SessionConfig
  Stores configurations we want to initialize a Session with.

Enums

• CurveGroup
  Corresponds to the various defined WOLFSSL_* curves
• Error
  The failure result of an operation.
• ErrorKind
  Extracts an error message given a wolfssl error enum. Abstraction over WolfSSL errors
• IOCallbackResult
  Result type to be returned by methods on IOCallbacks
• Method
  Corresponds to the various wolf*_{client,server}_method() APIs
• NewContextBuilderError
  Error creating a ContextBuilder object.
• NewSessionError
  Error creating a Session object.
• Poll
  The Result::Ok for a non-blocking operation.
• ProtocolVersion
  TLS/DTLS protocol versions
• RootCertificate
  Defines a CA certificate
• Secret
  Defines either a public or private key
• SslVerifyMode
  SSL Verification method Ref: https://www.wolfssl.com/doxygen/group__Setup.html#gaf9198658e31dd291088be18262ef2354

Traits

• IOCallbacks
  The application provided IO callbacks documented at EmbedRecieve (whose inputs and outputs we need to emulate). See also wolfSSL_CTX_SetIORecv which is the best docs for wolfSSL_SSLSetIORecv and wolfSSL_SSLSetIOSend, which are what we actually use.

Type Aliases

• Result
  Describes an outcome that is synchronous.
