Looks like encrypted using an (wrongly implemented) OTP.
Code:
def group(e, n=2):
res = []
for x in range(len(e)//n):
res.append(e[x*n:(x+1)*n])
return res
def parseEnc(e):
return list(map(lambda x: int(x, 16), group(e)))
def parseDec(e):
return list(map(lambda x: ord(x), group(e, 1)))
def getKey(a,b):
enc = parseEnc(a)
dec = parseDec(b)
assert len(enc) is len(dec)
res = []
for i in range(len(enc)):
res.append(enc[i] ^ dec[i])
return res
getKey("60727C60790863017F1D746072", "9999999999999")[:-2]
> [89, 75, 69, 89, 64, 49, 90, 56, 70, 36, 77]
getKey("6879766D75076D007F1D", "1234567899")
> [89, 75, 69, 89, 64, 49, 90, 56, 70, 36]

It's just simple "XOR encryption." The key is 594b455940315a3846244d.

This thread is getting all script-kiddie way too fast. We gave you way more help than we probably should have. We told you what type of "encryption" is used, and even gave you the key. You should be able to figure it out from here.
