Subject: Using PBKDF2-HMAC-SHA256

Hello,

I'm trying to get PBKDF2-HMAC-SHA256 hashes to be loaded. The example hash
below loads just fine.

$pbkdf2-sha256$12000$2NtbSwkhRChF6D3nvJfSGg$OEWLc4keep8Vx3S/WnXgsfalb9q0RQdS1s05LfalSG4

However, my hash below does not. I encoded the salt and digest with base64.
The raw data for simplicity:

       rounds: 100000
"salt": "e65814e4382759f85550029e723dc7e7",
"derived":
"5f37a3bd08ac1c7d163294a3cb192ed1407b62bbc6a6259fee55f6e53f754273"

My hash file:
$pbkdf2-sha256$100000$ZTY1ODE0ZTQzODI3NTlmODU1NTAwMjllNzIzZGM3ZTc=$NWYzN2EzYmQwOGFjMWM3ZDE2MzI5NGEzY2IxOTJlZDE0MDdiNjJiYmM2YTYyNTlmZWU1NWY2ZTUzZjc1NDI3Mw==

This is simply a test hash, I have the key. I just want to ensure that JTR
can properly work with the hashes before attempting to find keys for hashes
I do not know.

Any help?
