Crack, Decrypt numbers

[terexberd]

Hey i wanted to know if there's a program that shows u a pattern on how they got the number if i give them 3 examples? for Ex:

1) 35777903801230601 (Encrypted) = 46071642 (Decrypted)
2) 35777903248036801 (Encrypted) = 43975216 (Decrypted)
3) 35777903508068601 (Encrypted) = 91756761 (Decrypted)

That depends entirely on the encryption and hash algorithms used. Any current strong encryption method should NOT provide pattern-based clues to the plain-text. For more information about all of this, read Bruce Schneier's book "Applied Cryptography".

No. Insufficient data

There is also a book by Wenbo Mao which may be worth your time.
