Get error when trying to decrypt String from a ContentProvider

[DonalRafferty]

I am currently using your excellent code to encrypt and decrypt on Android, however I have hit an issue that I don't know how to resolve or what might be causing it.

When I use your code straight up where I encode and decode a simple String it works fine.

However what I need to do is encrypt the String, put it in a Content Provider and then decrypt it when I pull it from the Content Provider.

However when I pull it from the ContentProvider and try to decrypt it I get the following exception:

java.security.GeneralSecurityException: MAC stored in civ does not match computed MAC.

The exact same String works if I decrypt it without putting it into the Content Provider so I am unsure why I am getting this issue?

Can you help me find why this might be occurring?

Sorry my mistake it looks like its not using the correct key when the ContentProvider is called, sorry.

Not really sure what might be going wrong. If the exact same string
decrypts before but not after you put it in the content provider, best
guess is that it's not the same string.

Can you compare the two? Is it getting whitespace or markup added? Is it
getting truncated? Is it getting encoded with something like UTF 8?
