md5-hash-from-file example

Getting an md5 hash (fingerprint) from an input file using the standard crypto/md5 package. I also added a flag to read in your .ssh/id_rsa.pub key to get your ssh fingerprint. Your github uses this for verification.

Refer to the crypto/md5 package for more info.

RUN

go run md5-hash-from-file.go <FILENAME>
go run md5-hash-from-file.go test.txt

If you run on test.txt you should get,

HOW IT WORKS

Take a string plainText and turn into a md5 hash,

plainTextBytes := []byte(plainText)

// HASH
md5HashByte := md5.Sum(plainTextBytes)

// CONVERT TO STRING
md5Hash := hex.EncodeToString(md5HashByte[:])
