sha1 algorithm explanation with example

What is MD5, what is SHA-1, and how to verify these hashes. There is a single ISO document MD5,SHA-1 interrogation is not the original question, here, to do a final explanation of the above problems. Let's take a look at some basic knowledge about

Ask, If I transcode this way, is it more secure. For example: sha1 (md5 (password) I want to know: 1 is necessary. 2. if so, will it have a great impact on performance or what else I can't think, what problems may occur in the future, etc. I hope

Ask, I if this transcoding, is not security will be a little higher. For example: SHA1 (MD5 ("password")) What I want to know is: 1 is that necessary? 2 If this is possible, the impact on performance will be very large or other what I can not think

Hash table, also known as the hash table, is based on a fast access point of view design, but also a typical " space-time " approach. As the name implies, the data structure can be understood as a linear table, but the elements are not tightly
