7	Is the decompression of compressed and encrypted data without decryption also theoretically impossible?
2	How to prove that finding a cycle in a cryptographic hash function is hard?
1	Is it theoretically possible to construct a string that contains its own hash value?
1	Does anyone know of any programmes that can find a function from a known input and output?
