I've run into a very strange circumstance and figured I would post here because I have no clue what's wrong. I have developed this android app that involves passwords and I have a user with a saved encrypted AES string saved to a file. When a user logs into the system again with their password I need to see whether it equals the encrypted on already in the file.
So I grabbed it and tried to compare the two strings using the .equals method like always and to my surprise it didn't work.
Here are the two strings: What am I missing? Any help would be greatly appreciated since I don't even have an first step on how to solve this. I also tried compareTo == 0 and it didn't work either.
Thank you very much!!!
The first string is from the file, the second is the encrypted version of the password the user just entered:

o0JkTVCBcbZnePszCKp64/cOJx/W/dud/xszfvNjwGk=
Base64 encoding is used to encode binary data into strings; the base64 string is not the data itself. To compare the data in the strings, first decode it to a byte array, then compare the byte arrays using the utility function in the Java Arrays class. This should avoid issues with e.g. white space both in and around the encoding.
