The article argues that C remains the preferred language for cryptographic software due to its portability, ecosystem stability, and explicit low-level control, which are critical for security despite the rise of memory-safe alternatives like Rust. It emphasizes that mature crypto libraries rely more on rigorous testing and long-term validation than language-level memory safety. The piece contends that unsafe code is often unavoidable in cryptography, making abstraction layers in newer languages less beneficial.
Background
Cryptographic software requires high reliability, portability, and low-level hardware control, often leading to debates about language choices between C and modern alternatives like Rust. C has historically dominated this field due to its minimal abstraction and widespread compiler support.
