nelmio/alice random string with specified long

Question

I was trying to find way generate random unique string with 8 characters long using nelmio/alice.

And I've found only <uuid()> (token (unique): <uuid()>)method, unfortunately it returns too long string, I need just 8 characters.

May be some one knows elegant solution?

Thanks I've found solution

token (unique): '<( substr( md5( uniqid( rand(), true ) ) , 0, 8) )>'
