OpenSSL bindings for Rust providing cryptographic functionality and TLS/SSL support.
rust-openssl is a Rust library that provides bindings to the OpenSSL cryptographic toolkit, allowing Rust developers to incorporate security features like encryption, decryption, digital signatures, and TLS/SSL protocols into their applications. It solves the problem of accessing mature, battle-tested cryptographic functionality from Rust's type-safe and memory-safe environment.
Rust developers building applications that require cryptographic operations, secure network communication, or certificate management, particularly those who need compatibility with the widely-used OpenSSL library.
Developers choose rust-openssl because it provides direct, safe access to OpenSSL's comprehensive security features from Rust, combining Rust's safety guarantees with OpenSSL's industry-standard cryptographic implementations without requiring them to write unsafe C bindings themselves.
OpenSSL bindings for Rust
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides full bindings to OpenSSL's C API, including hashing, encryption, TLS/SSL protocols, and certificate management, as highlighted in the key features.
Wraps OpenSSL's unsafe C interfaces in Rust's type-safe and memory-safe APIs, reducing risks of common security vulnerabilities.
Leverages the widely-used OpenSSL library, ensuring interoperability with existing cryptographic systems and protocols.
Follows a predictable annual major release schedule with partial bug fix support for previous versions, as stated in the release support section.
Requires linking to the system's OpenSSL library, which can cause installation, versioning, and cross-platform compatibility issues.
Vulnerabilities in the underlying OpenSSL library directly impact rust-openssl, exposing users to potential security flaws from the C codebase.
As a binding layer, the API may not fully embrace Rust's ownership and error handling patterns, leading to a steeper learning curve for Rust developers.
