    copied!<p>Is the value in the Coldfusion ThisKey:</p> <pre><code>&lt;cfset ThisKey = "a-24byte-key-string-here"&gt; </code></pre> <p>The exact same string that is returned from the java generateKey() function? I believe they need to be to be the same string for the generated encrypted text to be the same.</p> <p>To use a fixed key like that in CF, you may need to follow this from the <a href="http://kb2.adobe.com/cps/546/e546373d.html" rel="nofollow noreferrer">CF technote</a> on strong encryption:</p> <blockquote> <blockquote> <p>You may want to generate your own key for two reasons:</p> </blockquote> <ol> <li>You want to match the details of other encryption software.</li> <li>You want to increase the resistance to cracking of your encrypted data by pattern-oriented cryptanalysis techniques.</li> </ol> <p>For example, to create a 32-byte key to use with the AES algorithm with the hex value:</p> <p>8738fed68e7677d374e0946c8f7bd3bb4f50f23717f9f3667b2419483959039c</p> <p>you would use the ColdFusion functions BinaryDecode and ToBase64 to create the key:</p> </blockquote> <pre><code>&lt;cfset myKey = ToBase64(BinaryDecode("8738fed68e7677d374e0946c8f7bd3bb4f50f23717f9f3667b2419483959039c","Hex")&gt; &lt;cfset encrypted =Encrypt(myString, myKey, "AES")&gt; </code></pre> <p>EDIT: Just realized that the key (as you mentioned in your comment) is base64, so if the "generateKey" method in Java looks like:</p> <pre><code>private static Key generateKey() throws Exception { final byte[] decodedKey = new BASE64Decoder().decodeBuffer(KEY_VALUE); final Key key = new SecretKeySpec(decodedKey, _AES); return key; } </code></pre> <p>You should be golden.</p>
