hash

A hash generator written in go

---

Usage:

hash <algorithm> <password>

Generate a hash of <password> using <algorithm>

---

Algorithms:

• Implemented by default

• Not implemented by default

• MD4

• MD5

• SHA1

• SHA224

• SHA256

• SHA384

• SHA512

• MD5SHA1

• RIPEMD160

• SHA3-224

• SHA3-256

• SHA3-384

• SHA3-512

• SHA512-224

• SHA512-256

• BLAKE2s-256

• BLAKE2b-256

• BLAKE2b-384

• BLAKE2b-512

Examples:

Valid usage:

• We use algorithm MD5 and password myPassword:
  ./hash MD5 myPassword
  Output: 3rFTb0gEdffVkyGaoa/XTA==

• Different password or hash algorithm will return another hash:
  ./hash MD5 testPassword
  Output: /tO2GyYIGEk3gICzTmk9Lg==

• We use algorithm SHA3-512 and password myPassword:
  ./hash SHA3-512 myPassword
  Output: e9NoZl7gdhx+atbv1M3I9ROijXEFim5qKa1Rwi3VXp0PiXcdCeCWHq7ptzTod29gpCd7tFWiPT1IRaMazItVOA==

---

Error messages:

• We use an invalid algorithm and password myPassword:
  ./hash SHA5 myPassword
  Output: Unknown algorithm

• We use a valid algorithm which is not implemented by default and password myPassword:
  ./hash MD5SHA1 myPassword
  Output: No implementation found

• We use only one or no command line arguments: ./hash
  This prints the usage:
  Output: Usage: hash <algorithm> <password>
