I want to say it's something like a Caesar shift because some of the lowest used letters in the English alphabet (z, k, and j, specifically) show up as the most used in that string.
No idea what would cause characters like ( and / to show up, unless you did a Caesar shift on ASCII values.

It's not encrypted using things like MD5 or SHA-1/SHA-2, and it's not BASE64.

edit: I think it might be that you used sentences that contain non-alphanumeric characters, transposed all the characters randomly, and then shifted all alphabetical characters to a different letter.
