This small golang app takes an input (password) and encodes it with SHA512.

go get github.com/tsedgwick/hash-api

CLI cli covers:

• The basic SHA512 encoding of a password via command line

  go run cmd/cli/main.go -password=angryMonkey

• Hash and Encode Passwords over HTTP (returns the encoded password back to the user)

    curl -X POST \
        http://localhost:8080/v1/hash \
        -H 'cache-control: no-cache' \
        -H 'content-type: application/x-www-form-urlencoded' \
        -d password=angryMonkey

    curl -X POST \
        http://localhost:8080/v2/hash \
        -H 'cache-control: no-cache' \
        -H 'content-type: application/x-www-form-urlencoded' \
        -d password=angryMonkey
