开发者_如何学JAVAGenerate MD5 hash in Java

Hi,

I want to compute the MD5 hash of a string in my scala code. Is there any scala or java library i can use to do this quickly, apart from the regular java.security.MessageDigest way ?

Please Help Thanks

You may be reinventing a very tiny wheel here, but just write a function to do what you want: take a string, use MessageDigest, and return whatever (hex string, byte array) you need.

import java.security.MessageDigest

def md5(s: String) = {
    MessageDigest.getInstance("MD5").digest(s.getBytes)
}

md5("Hello")

P.S. I don't write Scala, but this works and it's left as an exercise to the reader to turn it into anything other than an Array[Byte]
