A HMAC-SHA1 digest.

Pass a Key and a Message to compute a Digest

digest "key" "The quick brown fox jumps over the lazy dog"
    |> toHex
--> Ok "DE7C9B85B8B78AA6BC8A7A36F70A90701C9DB4D9"


digest "key" "The quick brown fox jumps over the lazy dog"
    |> toBase64
--> Ok "3nybhbi3iqa8ino29wqQcBydtNk="

Convert a Digest into elm/bytes Bytes. You can use this to map it to your own representations. I use it to convert it to Base16 and Base64 string representations.

toBytes (digest "key" "message")
--> Ok (<80 bytes>)

Convert a Digest into a List of Integers. Sometimes you will want to have the Byte representation as a list of integers.

toIntList (digest "key" "message")
    |> toIntList
--> Ok [32,136,223,116,213,242,20,107,72,20,108,175,73,101,55,126,157,11,227,164]

Convert a Digest into a base16 String Result

case toHex (digest "key" "message") of
    Ok base16String ->
        "Hex string: " ++ base16String


    Err err ->
        "Failed to convert the digest"


--> Hex string: 2088DF74D5F2146B48146CAF4965377E9D0BE3A4

Convert a Digest into a base64 String Result

case toBase64 (digest "key" "message") of
    Ok base64String ->
        "Base64 string: " ++ base64String


    Err err ->
        "Failed to convert the digest"


--> Base64 string: IIjfdNXyFGtIFGyvSWU3fp0L46Q=
