MD5 is not that secure compared to blowfish or twofish or the other types of encryption available with mcrypt...

What about MD5? MD5 is a message digest I believe, something akin to the oldstyle CRC32. Then again I haven't used it much (just to verify a client's credit card number without revealing the CC number).

I imagine he would want to un-encrypt his files at some point and MD5 is a one-way method and not an encryption technique at all... ---John Holmes... - Original Message - From: Javier [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, May 21, 2002 4:43 PM Subject: [PHP] Re: Mcrypt: Blowfish or Twofish or no fish? -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 What about MD5?

RE: [PHP] Re: Mcrypt: Blowfish or Twofish or no fish?
It is a one way hash that many people use for simple encryption...however, it should not be used for encrypting sensitive information...some people have used it for encrypting data contained in files... For example do a md5 hash then encrypt the hash Thanks, Ray Hunter -Original Message- From: Thalis A.

And yes...md5 is a message digest hashing utility for compact digital signatures for an arbitrarily long stream of binary data. MD5 website...
