# simple-crypto

Simple C lib of the MD5 & TEA algorithm

# Performance

Benchmark a `3.5MB` file comparing with `md5` command in `MacOS Mojave` by running three times `time` command then calculating their average.

```bash

# system command: total 22ms

real    0m0.015s

user    0m0.012s

sys     0m0.005s

# our md5 command: total 39ms

# build by

gcc md5.c -o md5 -O3 -DTEST_SIMPLE_CRYPTO

real    0m0.021s

user    0m0.013s

sys     0m0.005s

```

Our version is `17ms` slower than what system does.

Benchmark a `481.7MB` file comparing with `md5` command in `MacOS Mojave` by running three times `time` command then calculating their average.

```bash

# system command: total 2079ms

real    0m0.980s

user    0m0.964s

sys     0m0.135s

# our md5 command: total 2499ms

# build by

gcc md5.c -o md5 -O3 -DTEST_SIMPLE_CRYPTO

real    0m1.253s

user    0m1.003s

sys     0m0.243s

```

Our version is `400ms` slower than what system does.
