We run benchmark using criterion with libaes against RustCrypto crates aes + block-modes. The code is here.
The current result on MacBook Pro Mid-2015 with Rust 1.49, running cargo bench:
libaes 128 cbc encrypt time: [639.89 ns 641.24 ns 642.72 ns]
aes-block-modes 128 cbc encrypt
time: [2.2069 us 2.2125 us 2.2193 us]
libaes 128 cbc decrypt time: [664.92 ns 679.57 ns 696.55 ns]
aes-block-modes 128 cbc decrypt
time: [2.4734 us 2.4985 us 2.5264 us]
For AES-128 CBC mode, libaes is more than 300% faster than aes + block-modes.
