What kind of hash is this?

[Tinnuel]

Hello guys. I've been looking all day to figure this out, but no luck yet. I've run it through identifiers and such.

This key is from IOS 7, off of an iPhone 5s. I use the restrictions to remove unwanted apps, prevent me from accidentally buying in-app purchases, etc. Somehow I have forgotten the pin at this point and can't get back in. From what I gather, I could reset my phone, but I would have to set it up as a new phone (pain in the butt), and I would rather avoid that if all possible.

This is pulled from the com.apple.restrictionspassword.plist file

Code:

    <key>RestrictionsPasswordKey</key>
    <data>
    J94ZcXHm1J/F9Vye8GwNh1HNclA=
    </data>
    <key>RestrictionsPasswordSalt</key>
    <data>
    /RHN4A==
    </data>

The code is numerical pin with 4 figures XXXX

Any ideas? If so, how would I go about decrypting it (if its even possible)?

Thanks in advance.
