In 2023, Codethink added support for RISC-V's vector cryptography extension (crypto) to QEMU. These upgrades enhance cryptographic performance for operations like AES and SHA-2. Sponsored by SiFive, this project was a key step toward ratifying the extension. Read our blog post to discover how we tackled decoding, testing, and upstreaming this additional feature: https://buff.ly/3BN1c5l #RISCV #QEMU #opensource #cryptography
