Could you give more details on your code ?<br />
<br />
Right now, i assume that you should do the followings:<br />
<br />
...<br />
<br />
hash = MessageDigest.getInstance(<wbr />&quot;SHA-256&quot;)<wbr />;<br />
... <br />
// Calculate the hash<br />
byte[] digest = hash.digest(input);<br />
... <br />
// Base64-encode it before returning<br />
return Base64.encodeBytes(digest)<wbr />;<br />
<br />
<br />
If this is what you have done you should get the same result.

Yes it is exactly what I'm doing, but, for documentation that I read, it seems (I'm not sure) that Java does not have the SHA256 algorithm so I guess it is taken SHA1. Do you know if the framework has, in fact, &nbsp;built in support for SHA256?

<div class="content wysiwyg-content">
I've found a JavaScript that implements SHA256, the encoded64 string that it returns is fully compatible with the result I've got with C# cryptograhpy API, so I can hash strings on web browser, send them to the server and compare against C# hashed strings.<br />
<br />
Now I'm traying to do the same with Java but the API seems to produce a very different result. I thought that, if sha256 is a &quot;standard&quot; algoritm, results has to be the same.<br />
<br />
What can be happened? Are there any JavaScript &quot;compatible&quot; with Java API?<br />
<br />
I'm using MessageDigest.getInstance(<wbr />&quot;SHA-256&quot;)<wbr /> to do the hashing<br />
<br />
Thanks

What can be happened? Are there any JavaScript "compatible" with Java API?

SHA256 in Java

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
