# Bcrypt
## bcrypt no need to store salt?
The salt is automatically included in the output string which means there is no need to add it by yourself.
## Run
```bash
$ go run main.go
Password: secret
Hash: $2a$14$98XP6TZdyN6ir/q1I7yQLeQQvb60gajYQ9fdaNmb51Wgz4nSLB6oS
Match: true
```
## Unit test
```bash
$ go test
```
## Benchmark
BenchmarkHashPassword/password-16 410 63111774 ns/op 5199 B/op 11 allocs/op
- 410 is the number of iterations for i := 0; i < b.N; i++
- 63111774 ns/op is approximate time it took for one iteration to complete
- 5199 B/op allocs/op means how many distinct memory allocations - occurred per op (single iteration).
- 11 allocs/op B/op is how many bytes were allocated per op.
```bash
$ go test -bench=. -benchtime=20s -benchmem -cpu 1,2,4,8
