How to base64 encode a SHA-1 hash in Scala and Play Framework?

Faster and cleaner with Play api :

var signature = play.api.libs.Codecs.sha1(md.digest("Foo".getBytes))

Play 2.7 (possible also older versions)

var signature = play.api.libs.Codecs.sha1("Foo")

You seem to have forgotten a pair of parenthesis:

val md = java.security.MessageDigest.getInstance("SHA-1")
val ha = new sun.misc.BASE64Encoder().encode(md.digest(params.get("Foo").getBytes))

That should work better.
