问题 I'm trying to use the Jacksum API to generate a Whirlpool hash, but I'm getting a NoSuchAlgorithmException: import java.security.NoSuchAlgorithmException; import jonelo.jacksum.JacksumAPI; import jonelo.jacksum.algorithm.AbstractChecksum; public static String genHash(String inText) { AbstractChecksum checksum = null; checksum = JacksumAPI.getChecksumInstance("whirlpool"); checksum.update(inText.getBytes()); return checksum.getFormattedValue(); } I tried other popular algorithms (sha256, md5)

Which one is more secured md5 or whirlpool (hashes) and Why?

问题 I am very much new in this cryptography section. I want to raise a question here regarding md5 hashes and whirlpool hashes. So far I have found that md5 can be broken and hence it is not safe to use. I also learned a little bit about whirlpool hashes. Now, my question is "Which one is more secured?" except knowing that md5 can be broken. One more question, i need to know any applications that use both md5 and whirlpool hashes in their program. It would be really helpful for me if anyone can

问题 Im trying to make a Vortex effect on a Circle Body that is a Sensor. I've been looking for this and all examples i look for are in C++ or Objective C and i dont seem to translate them well. when my objects collition, it calls beginContact(..) and it sets a flag so that i can call bodyToUpdate.applyForce(...); public void beginContact(Contact contact) { setColliding(true); } //updating collition every frame public void act(){ if (colliding) { ball.getBody().applyForce(....); } how to calculate

Edit: so i now have the object going
