Crate wolfssl

Expand description

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

Structs§

Aes256Gcm: Struct for encrypt/decrypt using Aes256Gcm cipher
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.

Aes256GcmError: The failure result of an operation.
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

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.

get_wolfssl_version_string: Get WolfSSL version via LIBWOLFSSL_VERSION_STRING header defined in wolfssl/version.h
