The password will have to be encrypted (not hashed), using some other encrytion format and some sort of key will be needed. These sort of method is, normally, not as secure, though.

SHA-2,MD5? Programming Computer Science by charles nitro SHA and MD5 are different algorithms. SHA is considered more secure than MD5. And it doesn't matter if you are talking about the implementation of the algorithms that is distributed with PHP or any implementation. They produce the same result md5 in php produces the same result as md5 in any other language. Re: best encryption algorithm? SHA-2,MD5?

Re: SHA-256 in .NET Programming Software Development by IIMarckus My problem is not with the concept -- I've done this sort of thing before in PHP -- but with the syntax.

The byte array needs to be hashed with all combinations of a minimum of 4 bytes to a maximum of all 9 bytes of the following bytes: 00 01 02 03 04 05 06 07 08 So the following are some examples of the byte array that would need to be hashed using a sha-1 hash: 00 01 02 03 00 01 02 04 00 01 02 … Re: Simple sha-1 encryption using openMp Programming Software Development by n@nnouss@ …#include <iostream> #include "sha1.h" #include <string> using…void DisplayMessageDigest(unsigned *message_digest); int main() { SHA1 sha; unsigned message_digest[5]; sha.Reset(); sha… Why I can't access the web pages by IE (HTTPS with DES-CBC-SHA?)
