The register arguments to the AESE instruction are commutative, however the first input register is constrained in that it also names the output register. The constraint on register allocation causes recent LLVM versions to emit a lot of MOV instructions, significantly impacting performance. Swapping the register operands allows the compiler to emit significantly fewer MOV instructions. This change improves performance on Arm infrastructure micro-architectures by 14-36% depending on the micro-architecture Found and reported by George Steed from ARM. Thanks!
Sodium is an easy-to-use software library that provides a wide range of cryptographic operations including encryption, decryption, digital signatures, and secure password hashing.
It is a portable, cross-compilable, installable, and packageable fork of NaCl. While maintaining API compatibility, libsodium extends functionality to improve usability and simplify the development of secure applications.
Key Features
- Encryption & Decryption: Securely encrypt and decrypt data with modern algorithms.
- Digital Signatures: Create and verify signatures to ensure data authenticity.
- Cross-Platform Compatibility: Supported on Windows (MinGW and Visual Studio, both x86 and x64), iOS, Android, JavaScript, and WebAssembly.
- User-Friendly API: Designed to provide all core cryptographic operations while remaining easy to integrate into your projects.
