Does anyone have experience with the crypto-api package?
It seems to define a nice common API for block ciphers, hash functions and prng's. However, I get very low performance using it.
I ran its benchmark on a NOP block cipher, where encryptBlock k = id, and it's still very slow.
After expanded the included block cipher benchmark (which uses ECB) to include CBC and CTR I got the following: ECB: 30 MB/s -- somewhat slow CBC: 12 MB/s -- very slow CTR: 4 MB/s -- why is adding a counter so bad?
Have anyone else benchmarked this and if so with what results?
Neither benchmarked nor used it, but just to make sure: did you notice that the comment says 128KB strings for ps and lps, but they are in fact 1MB strings: -- 128KB strings ps = B.replicate (2^20) 0 lps = L.replicate (2^20) 0 ? If not, the throughput would look much better, wouldn't it?
