Re: Long string to short ID

How about:

1> lists:flatten([integer_to_list(V,16)||<<V>> <= crypto:hash(md5, "really long book title that goes on and on forever")]).
"C72BFE8643B0156ACD809D87D51E726C"

OR

2>  binary_to_list(base64:encode(crypto:hash(md5, "really long book title that goes on and on forever"))).
"xyv+hkOwFWrNgJ2H1R5ybA=="

Subject: Long string to short ID

Hello,

What might be a nifty way to turn a long book title with spaces into a short human-readable ID?

Thanks,

LRP
