Unable to verify signatures created with a seed

[talios]

Calling caesium.crypto.sign/keypair! with a byte[] seed seems to trigger verification failures with verify(sign ...)...).

I modified one of the test cases in sign-test.clj as seen in https://gist.github.com/talios/d0ea678b0ce5b044ec48c6074855cf6a which triggers the problem.

Is this not the correct way to generate a keypair with a common seed, which will survive VM restarts?

Thanks for your report! I'm looking into this.

The obvious problem is that the seed has to be seedbytes (is, to wit, 32), but that shouldn't matter for that example.

Looks like it's a length problem:

caesium.crypto.sign> (let [{pk :public sk :secret} (generate-signing-keys (.getBytes "secret"))]
      (verify (sign (.getBytes "hi") sk) (.getBytes "hi") pk)
    )
java.lang.RuntimeException: Signature validation failed
caesium.crypto.sign> (let [{pk :public sk :secret} (generate-signing-keys (.getBytes "YELLOW SUBMARINEYELLOW SUBMARINE"))]
      (verify (sign (.getBytes "hi") sk) (.getBytes "hi") pk))

not sure why it doesn't just read 32 bytes past the pointer, though... (Although it still wouldn't be repeatable)

@lvh should that error out/throw an exception is < seedBytes? That'll let me move on my own issues tho.
