Ghas

an attempt at creating a usable Hashing Algorithm

---

• running sample main go run ghas.go -f $FILE_PATH -s $HASH_SIZE

Usage of ghas:
  -v    verbose mode, to enable file length & time taken info for GHAS
  -c    prints comparative hash from MD5, SHA256, SHA512, HMAC with time taken (enables verbose by default)
  -f string
        path of file to hash
  -s int
        size of hash to generate (default 64)

example: go run ghas.go -f ./LICENSE -s 256 -c will show time taken and hash calculated by this Ghas alongwith comparative calculation by Golang libs for md5, sha256, sha512, hmac

sample run estimates from an avergae laptop are at benchmarks.md

• running unit tests, coverage, benchmark & dropping on pprof is covered by test.sh
