MD5 Hash Online Generador

I am trying to create a url using md5 in python3 similar to php https://www.w3schools.com/php/phptryit.asp?filename=tryphp_func_string_md52For Binary format i get in php code as TRUE - Raw 16 character binary format: ��S�a��'���x�.I tried this code

str1 = "Hello"test = hashlib.md5(str2hash.encode("utf-8")).digest()`enter code here`print(str( test))

and I tried hexdigest() also But i get output in this wayb"\xa7\xcd\xc8\xd9r\xca'\xd7X\xd6\xe1\x11\x03>\xf0\xda"b'8b1a9953c4611296a827abf8c47804d7'How do i get it in same Raw 16 char binary format?

It doesnt match the php output and hence it fails

i'm using MD5 hashing to encrypt passwords for a program. But it is not creating all the characters and that to some are unreadable.Here is an screenshot.link-http://i46.tinypic.com/2qvf2o2.jpg

Any help is appreciated

Thanks

What would be the fastest and more robust (in terms of uniqueness) way for implementing a method like

public abstract String hash(String[] values);

The values[] array has 100 to 1,000 members, each of a which with few dozen characters, and the method needs to be run about 10,000 times/sec on a different values[] array each time.

Should a long string be build using a StringBuilder buffer and then a hash method invoked on the buffer contents, or is it better to keep invoking the hash method for each string from values[]?

Obviously a hash of at least 64 bits is needed (e.g., MD5) to avoid collisions, but is there anything simpler and faster that could be done, at the same quality?

For example, what about

public String hash(String[] values){    long result = 0;    for (String v:values)    {        result += v.hashCode();    }    return String.valueOf(result);}

I want to know if the MD5 digest algorithm is guaranteed to be available in all Android devices before I bluntly ignore the checked exception that MessageDigest.getInstance("MD5") can throw.

Someone told me that he has seen software systems that:

1. retrieve MD5 encrypted passwords from other systems;
2. decrypt the encrypted passwords and
3. store the passwords in the database of the system using the systems own algorithm.

Is that possible? I thought that it wasn't possible / feasible to decrypt MD5 hashes.

I know there are MD5 dictionaries, but is there an actual decryption algorithm?
