How about Fleence (from Macbeth), or bleen (from whale taxonomy)?
lol this has to be a joke right? bleen? fleence? why not bleenfleence?
Sorry, I don't really have anything better, and I don't mean to ridicule. I have to agree with anonymint (and I do hold a little bbr) that rune is no bueno, imo. I like boolberry. If people don't like the berry, maybe boolring? Not boolshit. Boolring could be XBR, close to same ticker.

Enciphering sounds decent. Certainly has a nicer ring than rune, secore, or vortex to my ear, and incorporates "ring", which is at least relevant.
