hmac-signer --key <base64-encoded-key> --text <text-to-sign> hmac-signer understands these options:
--algorithm string, -a string
hash function used for signature (sha1, sha256 or sha512) (default "sha256")
--key bytesBase64, -k bytesBase64
key encoded as Base64 used to sign the data
--text string, -t string
plain-text that will be signed
--help, -h
