This page will help you identify the type of cipher you have.
You can use different measures for testing different properties of the text.
Index of Coincidence - Can detect if text has been put through polyalphabetic cipher. For english text, a typical value is around 0.067, but anything between 0.06 and 0.07 is normal. If it has been put through a polyalphabetic cipher like vigenere, it will be closer to that of random data, i.e. closer to 0.04.
Chi Squared - Can detect if text has been put through a substitution cipher
Stepped IOC - can be used to find keylen of polyalphabetic cipher (low range also implies not polyalphabetic)
Missing Characters - some ciphers use an alphabet of 25 characters. If this is detected it significantly narrows down the possibilities
IMPORTANT! this assumes all text is lowercase and processed (i.e. whitespace removed)
