Hi All,
I have a password file , which has all the passwords words encrypted with the Crypt Function
I know that Crypt uses one-way algorithm to generate the encryptions and PHP has no Decrypt function , ( but can it be developed to have one ?)
But I am eager to know whether it is really impossible to decrypt the passwords , if possible , how it caqn be done. like salts and all
Can somebody *please* throw more light on Crypt() and Encryption and Decryption in this thread.
Thanks,
Nikhil
As far as I know the standard crypto-methots used in crypt() is one-way-hashing. The data used when encrypting is lost, the encrypted data is generated using this data. There is no other methods to get these data back other than brute-forcing (guess, encrypt with the same algorithm and compare) but it may take months/years depending on the size of the orginal data.
