Hello everyobody,
I'm trying to do a presentation of MD5 algorithm in my class.
I would like to give an example of md5 hash in every programming language.
I found a useful website like md5-sha with examples in all other languages, but i still want to present Java too du to its wide use.
Thank you for helping.

Solution 2 is correct. You can use SHA-3 already: ripple-lib-java/SHA3.java at master · ripple/ripple-lib-java · GitHub[^].

And this is SHA-2: Google Code Archive - Long-term storage for Google Code Project Hosting.[^].

Both SHA-2 and SHA-3 are considered reliable. Please see:
SHA-2 — Wikipedia, the free encyclopedia[^],
SHA-3 — Wikipedia, the free encyclopedia[^].

Solution 2

Consider that both MD5 and SHA1 are both considered "broken" and should not be used for any security purpose what-so-ever. Using them to "secure" a password is considered bad practice and a security risk.

Correct, a 5, but it lacks positive suggestions; I added some in Solution 3.
