Subject: [PATCH] Fixes a bug in the test_pbkdf2_hmac_sha256 test.

This bug fix sets the length of the derived key in the last test_pbkdf2_hmac_sha256 test to 40 bytes to fix a buffer overflow, which is caused by the call to the pbkdf2_hmac_sha256 function, on the memory reserved by the local variable k.
