Unable to open encrypted realm in realm studio

Goals

I am trying to use a 64 bit hash string generated at https://passwordsgenerator.net/sha256-hash-generator/ and use the following method to convert it into byte array.

function toByteArray(str) {
	var array = new Int8Array(str.length);
	for (i = 0; i < str.length; i++) {
		array[i] = str.charCodeAt(i);
	}
	return array;
}

Later we pull the realm db and use the 128 length hex string generated from the hash (http://www.convertstring.com/EncodeDecode/HexEncode) to decrypt. After doing this, the decryption is failing with error -> Realm file decryption failed.

A weird thing is this whole process is working for me when I use this key which I found randomly online. lyNZHNHP7LDv17An6pOxADNLKYYqXYoQHxtmjjacTDR5RlkEbiJ2ELgJmRJ6/g== The rest of the process was all same. Instead of using a 64 bit hash string, I was using the above key

Version of Realm and Tooling

I can’t reproduce the error - instead I did this:

1. On https://passwordsgenerator.net/sha256-hash-generator/ I generated the hash 9B96A1FE1D548CBBC960CC6A0286668FD74A763667B06366FB2324269FCABAA4 which matches the passphrase hi there.
2. I used a script which used your function to generate a Realm (I’ve uploaded this to WeTransfer here https://we.tl/W6ScTQWrfR):

   const realm = new Realm({
     toByteArray("9B96A1FE1D548CBBC960CC6A0286668FD74A763667B06366FB2324269FCABAA4"),
     path: realmPath,
     schema: [SomeClass],
   });
   

3. I used http://www.convertstring.com/EncodeDecode/HexEncode to convert the phrase into a its hex representation: 39423936413146453144353438434242433936304343364130323836363638464437344137363336363742303633363646423233323432363946434142414134 and successfully opened the Realm using Studio.

I know it is old issue, it might help someone.

I had same issue as well, what i found out that you can’t access the encrypted realm file with multiple process. So if you are trying to access your file while your simulator opened the realm file. You should close the realm file from your simulator and try to access with realm studio.
