php and VC++ compatible encryption algorithm???help please

[xxhimanshu]

:confused:Hi All, I need to decrypt a file encrypted by a php script..it can be any algorithm which is good enough and cannot be cracked easily..if it cannot be cracked at all will be the best solution..but for now i am just looking for any of the MCrypt encryption algorithm that can encrypt the data good enough not to be cracked..easily...and that can be decrypted easily using VC++...can someone help me out in doing the same..I need it very urgently...any of the algorithm..Rijndael..or Blowfish or anyone..but it can also be decrypted easily..Any help or pointers are highly appreciated... Thanks a lot.. Regards :confused: :confused: Himanshu

Have you tried md5() ? I know of at least 2 VC 6.0 classes that can work with the hash. But that is not the same as true encryption. I wrote one called blackhorse a few years back. If you want to use please email direct. Best Wishes, ez_way

you have plenty of algorithms - you named few of them Blowfish, RC4, 3DES... choice is up to you - most of these algos are proven and verified by time. If you have enough CPU time you can consider using asymetric cryptography. None of the mentioned algos was cracked if it was used with reasonable key size. Only problem you'll probably have is the key management ;-)

Just for clarifying, not to be offensive - if you 'encrypt it' with md5 you'll not able to get the plaintext back from the 'ciphertext'. That's why md5 is called one-way. There's no way back.
