can anyone help me with this cipher?

Question

it is possibly a frequency analysis cipher

Answer 1

Actually a quick check shows that the letters in your cipher are close to standard letter frequencies so I doubt it is a substitution cipher.

FREQUENCIES(in %)

In Message In English
E: 11.7 e: 12.7
T: 10.3 t: 9.1
O: 9.4 a: 8.2
A: 7.9 i: 7.0
N: 7.7 n: 6.7
I: 6.3 o: 6.3
H: 5.9 h: 6.1
R: 4.9 r: 6.0
S: 4.9 d: 4.3
L: 3.7 q: 4.3
D: 3.6 l: 4.0
Y: 3.6 c: 2.8
M: 3.1 u: 2.8
U: 3.0 m: 2.4
W: 3.0 w: 2.3
C: 2.4 f: 2.2
G: 1.7 s: 2.2
F: 1.6 g: 2.0
B: 1.3 y: 2.0
V: 1.3 p: 1.9
K: 1.1 b: 1.5
P: 1.1 v: 1.0
J: 0.4 k: 0.8
X: 0.1 j: 0.2
Q: 0.0 x: 0.1
Z: 0.0 z: 0.1

Basically what it implies is that the letters are scrambled in some manner, but are what they are. Most likely it is a transposition cipher.

Any more details on where this came from, the possible methods of rearranging, anything else that would be useful in cracking it?
