Third-party Cryptography Providers

In addition to the providers listed in the README there are a number of third-party cryptography providers available for Rustls.

These projects have not been evaluated by the Rustls maintainers, and no claim is made to their production worthiness or overall quality.

Repository	Description
`rustls-graviola`	a provider that uses `graviola` for cryptography.
`rustls-symcrypt`	a provider that uses Microsoft's SymCrypt library.
`rustls-openssl`	a provider that uses OpenSSL for cryptography.
`boring-rustls-provider`	a work-in-progress provider that uses `boringssl` for cryptography.
`rustls-ccm`	adds AES-CCM cipher suites (TLS 1.2 and 1.3) using `RustCrypto`, for IoT/constrained-device protocols (IEEE 2030.5, Matter, RFC 7925).
`rustls-mbedtls-provider`	a provider that uses `mbedtls` for cryptography.
`rustls-pure`	a pure-Rust provider (no C or assembly) using `RustCrypto` primitives: TLS 1.3 only, ECDSA and Ed25519 certificates, tested against Wycheproof vectors.
`rustls-rustcrypto`	an experimental provider that uses the crypto primitives from `RustCrypto` for cryptography.
`rustls-scytale`	a provider that uses `scytale` for cryptography.
`rustls-wolfcrypt-provider`	a work-in-progress provider that uses `wolfCrypt` for cryptography.
