Encryption puzzle

[Shane Burgel]

Can you figure out how to decrypt this?

(I got bored and wrote an encryption program today that uses a standard technique and if you are anything like me you love puzzles so here you go)

using this brute-force shift cipher in javascript I can't get a solution ^^

var z="abcdefghijklmnopqrstuvwxyz",r=z.split(""),i=0,
enc="xmzzxprpxrwhfgimafbtreazsmef",dec=[],cur="",j;
for(;i<26;i++,cur="") {
  r.push(r.shift());
  for (j=0;j<enc.length;j++) cur+=r[z.search(enc[j])];
  dec.push(cur);
}
r.reverse();
for (j=0;j<enc.length;j++) cur+=r[z.search(enc[j])];
dec.push(cur);cur="";
for(i=0;i<26;i++,cur="") {
  r.push(r.shift());
  for (j=0;j<enc.length;j++) cur+=r[z.search(enc[j])];
  dec.push(cur);
}
r.reverse();
for(i=0;i<26;i++,cur="") {
  r.unshift(r.pop());
  for (j=0;j<enc.length;j++) cur+=r[z.search(enc[j])];
  dec.push(cur);
}
r.reverse();
for(i=0;i<26;i++,cur="") {
  r.unshift(r.pop());
  for (j=0;j<enc.length;j++) cur+=r[z.search(enc[j])];
  dec.push(cur);
}
dec

Yep, it's not a shift. It's polyalphabetic. Keep trying!

I got it. It decrypts to "Oh what a tangled web we weave, When first we practice to deceive!"

Now, you just have to figure out my decryption method that got me that result!!!

LOL, here's a hint. It's encoded using a Vigenere Cipher.
