SHA-2,MD5? 11 Years Ago 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?
