InvalidKeyException when setting encrypt-data = true

I get

java.security.InvalidKeyException: Invalid AES key length: 18 bytes

when setting encrypt-data = true. Without encryption, the library works fine. I'm using

"com.softwaremill.akka-http-session" %% "core" % "0.2.4"

with Scala-2.11.8.

Can you try 0.2.5-SNAPSHOT? The secret was incorrectly shortened to 16 bytes, things broke when a character was multiple-byte (as I suppose is the case with your secret)

[mlangc]

Upgrading to 0.2.5-SNAPSHOT does indeed solve my problem, thanks!

Great, 0.2.5 should be in central soon
